Question

http://prntscr.com/aozilv can someone just give me the steps i dont need an explaintion plz help

Answer 1

Well what is the formula for finding the area, this comes first.

Answer 2

A=28?

Answer 3

Close A=πr^2

Answer 4

Or in our case A = 22/7r^2

Answer 5

ok

Answer 6

for this u have to do steps to solve the problem

Answer 7

like step 1 and u know etc

Answer 8

Step 1:
Calculate the length of the radius. If you only know (or have measured) the diameter (the distance from one side of the circle to the other), then divide it by two to obtain the radius. The radius of a normal circle is always one-half of the diameter.
Step 2:
Read the formula. The formula for finding the area of a circle is
Area equals pi multiplied by (r squared)
Step 3:
Multiply the radius by itself to square it. For example, if your radius was 6 cm, your radius squared would be 36 cm squared.
Step: 4
Multiply the result you get from Step 3 by pi. (Use this also in "Finding the Area of a Sector").
If the instructions say "leave in terms of pi" or "exactly", then just stick the pi onto your answer (for example, the area of the circle = π36 cm^2.) If you just round it to 3.14, it's not at all exact. There is no way to show it exactly besides leaving the pi sign.
If the instructions say anything about rounding, replace pi with 3.14 or use your calculator's pi button.

Answer 9

This is for regular PI

Answer 10

im talking about the question

Answer 11

I know but out of these steps you should be able to DIY (Do it yourself) with 22/7

Answer 12

Estimate the area of the circle. Use 22/7 for pi

Answer 13

do u know step 1 for the question to solve it

Answer 14

Area equals 22/7 multiplied by r^2

Answer 15

k thats the first step?

Answer 16

Should be.

Answer 17

ok second?

Answer 18

Multiply the radius by itself to square it.

Answer 19

Then. Multiply the result you get from Step 3 by 22/7

Answer 20

That should be all the steps > First step > Calculate the length of the radius. If you only know (or have measured) the diameter (the distance from one side of the circle to the other), then divide it by two to obtain the radius. The radius of a normal circle is always one-half of the diameter.
