Answer:

Circumference: 31.4 ft

Area: 78.5

Explanation:

To do the circumference of a circle, you have to do 2
\pir, let's do 2x
\pi=6.28. Now we will do 6.28x5= 31.4, So 31.4 ft is the answer.

To do the area of a circle you have to do
\pir² so
\pix r². First we will do the radius first, 5x5=25, so we will do 3.14x25=78.5. So 78.5ft is the answer!
