Question

Find the area of a circle with a circumference of 32 yards

Answer 1

Hello!

Ok so we just need to play with the circle formulas a bit to spit out the answer here.

A=
`\pi r^(2)` and C=2
`\pi r`. We need to use these to get the radius of the circle.

32=2
`\pi r` just divide 32 by
`2\pi`. Making the radius about 5. Now we use the area equation,

A=
`\pi r^(2)` but r is 5 here so the area is 25 times
`\pi` which is 78.5398163...

Hope this helped!
