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

This is answer A.1188
B.1200
C.1220
D.1224​

Answers

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

Find the measure of b.

A. 70
B. 110
C. 75
D. 100

Answers

the answer is 75 because 180 is a full circle. so 180 minus 105 since it’s the opposite side which makes b 75

Answer: C. 75

Concept:

Here, we need to know the idea of quadrilaterals in a circle.

The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

Given information

The opposite angle of b = 105°

Given expression

b + opposite angle of b = 180°

Substitute values into the expression

b + 105 = 180

Subtract 105 on both sides

b + 105 - 105 = 180 - 105

b = 75°

Hope this helps!! :)

Therefore, there are 35 sets in the paragraph.

So, 35 x 3 = 105 are consonants and

hillary is cycling across montana taking a 845 mile course . the first week she covered.320 miles. the second week she traveled another 350 miles. how many more miles does she have to travel to complete course?

Answers

Answer:

175 miles

Step-by-step explanation:

Hillary has travelled

320 + 350 = 670 miles

in the first two weeks.

Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.

670 + x = 845

And if we subtract 670 from both sides:

x = 845 - 670 = 175

175 miles

This is just a huge vent so you can leave already I just need to tell this to something or someone to make my chest stop hurting.. It's pretty hard for me to live I don't know what condition this is or if it even is a condition. I don't even want to hear the word condition anymore it makes my head hurt like It never has before. It's hard for me to live my everyday life like I used to, and that's because I just can't bear the emotional pain of getting scolded or slightly told something negative about myself or what I'm doing. It gets hard to breathe sometimes and I start breathing rapidly and can't calm down. I don't think it's anxiety but It's pretty close.. people on the internet make it hard to keep my thoughts clear because I yell at myself in my head that I'm just faking it like others are on the internet and beat myself up, even more, when my heart starts hurting and it gets hard to breathe. It's also hard to feel any other emotions for long, like feeling happy, or thankful.
