Answer:
254.4
Step-by-step explanation:
if its 0.75 inch thick, then to get the radius you just times to thickness by 2 which gets 1.5.
6-1.5= 4.5
to get the radius you divide 4.5 by 2 which gets 2.25
and then put this in the formula you get=
V=πr2h=π·2.252·16≈254.469
so the answer is 254

The tables represent two linear functions in a system. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22) tables represent two linear functions in a system. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22) is deciding which of two gyms to join. Each gym charges a monthly rate plus a one-time membership fee. Lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. In her work, she substituted an expression for one variable and solved for the other. This resulted in the equation 75 = 75. What can Lian conclude? One gym charges $75 per month. Each gym charges $75 per month. Both gyms charge the same monthly rate and the same membership fee. Both gyms charge the same monthly rate, but not the same membership fee.
Answer:
We want to solve a system of linear equations, we will get that the solutionis (8, -22)A system of equations is a group of equations that we must solve simultaneously. Here we have two lines defined by tables:line 1:x y-4 26-2 180 102 2line 2:x y-4 14-2 80 22 -4Remember that a line is written as:y = a*x + bWhere a is the slope and b is the y-intercept.We know that if a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:With this we can find the slope of the first line, using any pair of the given points, I will use (0, 10) and (2, 2)And we know that the line passes through (0, 10), then the y-intercept is equal to 10.y = -4*x + 10For line 2 we can use the points (0, 2) and (2, - 4), so we get:And the y-intercept is y = 2, then the line is:y = -3*x + 2Now we must solve:-4*x + 10 = -3*x + 210 - 2 = 4x - 3x8 = xNow we evaluate x = 8 in any of the two lines:y = -3*8 + 2 = -22Then the solution of the system is (8, -22)
Jonny's bedroom has an area of 90 square feet. What might the length and width of his bedroom be
Answer: 30 on both.
Step-by-step explanation: 30 because 3x3 is 9 so then add a zero
Answer: Area is length multiplied by width.
90=10×9
Step-by-step explanation: The sides will be multiplied to get the area.

The ceiling of Stacy's living room is a square that is 33 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 33 ft, but she doesn't know how long it is.
Solve for the length of the diagonal of Stacy's ceiling in two ways:
(a) Using the Pythagorean Theorem.
(b) Using trigonometry.
Round each answer to the nearest whole number and make sure to show all your work. (Hint: the answers should be the same!)
Answer:
47
Step-by-step explanation:
a)
a^2 + b^2 = c^2
33^2+33^2=c^2
2178=c^2
c=(nearest is 47)
b)
If you cut the square in half diagonally, it forms two right triangles with angle measures 90-45-45. You can use sin (opposite over hypotenuse) to find the length of the hypotenuse. sin (45) would be 33/(hypotenuse length). From a trig chart, you can find that sin (45) is 1/sqrt(2), meaning that 33/x = 1/sqrt(2). This means that x=33sqrt(2), which is around 47.
The length of the diagonal of Stacy's ceiling is 46,7.
What is the Pythagoras theorem?Pythagoras Theorem (also called Pythagorean Theorem) is an important topic in Mathematics, which explains the relation between the sides of a right-angled triangle.
The ceiling of Stacy's living room is a square that is 33 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 33 ft, but she doesn't know how long it is.
By using Pythagoras theorem;
[tex]\rm Hypotenuse ^2=33^2+33^2\\\\ Hypotenuse ^2=1089+1089\\\\ Hypotenuse ^2=2178\\\\ Hypotenuse =46.9\\\\[/tex]
By using trigonometry;
[tex]\rm Cos45=\dfrac{33}{d}\\\\d =\dfrac{33}{cos45}\\\\d=46.7[/tex]
Hence, the length of the diagonal of Stacy's ceiling is 46,7.

jack and his 3 friends each ate 3pops on Monday if they all at the same amount the rest of the week how many pops could they eat in 3 weeks??
Answer:
216pops.
Step-by-step explanation:
If Jack and his 3 friends(4people total) ate 3 pops on Monday and ate 3pops for the rest of the week, that'd be 12 pops 1 day, and 12x6 is 72 then you have to multiple 72 by 3 and you get 216pops in 3weeks

If the walls of a square room require 480 ft^2 of paint and the floor to ceiling height is 10
ft, what are the dimensions of the room?
After find the area of one side, we proceeded to find the length and with as
Length = 10.95 feet width = 10.95 feet
Mensuration of ShapesGiven Data
Height of the Room = 10 feetArea of 4 sides of the room = 480 ft^2If the area of 4 side = 480 ft^2
Area of 1 side will be = x
Cross multiply we have
x = 480/4
x = 120 ft^2
Let us find the length and width of the room
x = √120
x = 10.95 feet
hence Length = 10.95 feet
width = 10.95 feet
Height = 10 feet

what is the mean of 25 31 12 38 12 15
Answer:
22.1666666667 ~ 22.17 (This should be rounded)
Step-by-step explanation:
The mean formula is to add all the numbers and then divide by the quantity or how many numbers were listed.
25+31+12+38+12+15/6 = mean
All the numbers added up should equal 133
You need to divide the sum by 6 since that is how many numbers that are in your data set.
The Mean of the Data set is 22.1666666667 which is approximately 22.17
