What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well, thank you.

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

hope it helped

5+3+8 or if its wrong then 5+3+8+5+3 or just one 3.
