A cylinder has a base area of 154 cm² and a height of 20cm. What is its total surface area, in cm?? Use, 22/7
A.1188
B.1200
C.1220
D.1224​

Answers

Answer 1

Answer:

Hi there!

We've given with the base area and height. We know the formula for base area

Base area = πr²

154 = 22/7 × r²

154 × 7/22 = r²

49 = r²

√49 = r

7 = r

Now

TSA = 2πr(h + r)

TSA = 2 × 22/7 × 7(7 + 20)

TSA = 44(27)

TSA = 1188 cm²

Answer:

All four sides of a square are equal in length, all interior angles of a square are right angles, all sides are parallel to an opposite side

Step-by-step explanation:

These are just 3 simple properties of many properties of a square. Obviously, a square is a quidrilateral that has four equal sides. Therefore, it makes all interior angles of the shape the same. And it is also a parallelogra, meaning that opposite sides are parralell to one another.

Answers

Answer:

[tex]x \leqslant 13[/tex]

Step-by-step explanation:

[tex] - 9 + x \leqslant 4 \\ x \leqslant 4 + 9 \\ x \leqslant 13[/tex]

Hello!

For this type of problem, treat the “less than or equal to” sign as an equal sign!

So, -9+x=4

Now, it is as simple as solving for “x” just like a regular algebra problem. Add 9 to both sides to get “x” by itself:

-9+x+9=4+9

Now you have:

X= 13

Plug the “less than or equal to” sign back into the equation:

X ≤ 13

Answers

Step-by-step explanation:

1. Let the number be a

3a = -10 - 2

3a = -12

a = -12/3 = -4.

2. Let the number be x

3x + 20 = 11

3a = 11 - 20

3a = -9

a = -9/3 = -3

3. Let the number be n

f (8^9)p = 8^18, what is the value of p? (5 points)
A 2
B 9
C 10
D 18

Answers

Answer:

A

Step-by-step explanation:

I'm assuming p is an exponent.

You can multiply the exponent p with 9

8^9p = 8^18

Now we know that some number times the exponent 9 gives us 18.

Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)

therefore, 9p=18

p=18/9

p=2

The average of five numbers is 34. Two of the numbers are the same, and the other three are 49, 25, and 42. Find the value of the two numbers missing numbers.

Answers

Answer:

Both numbers = 27

Step-by-step explanation:

( x + x + 49 + 25 + 42)/ 5 = 34          Multiply both sides by 5

(2x + 49 + 25 + 42) = 34*5 = 170     Combine the left

(2x + 116) = 170                                 Remove the brackets.

2x + 116 = 170                                   Subtract 116 from both sides

2x = 170 - 116

2x = 54                                             Divide by 2

x = 54/2

x = 27

Check

27 + 27 + 49 + 25 + 42

170 / 5 = 34

It does check out.

27 is right.

Option A "4, 6, 8".

This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.
