Answer:
Circumference: 31.4 ft
Area: 78.5
Step-by-step explanation:
To do the circumference of a circle, you have to do 2r, let's do 2x
=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 r² so
x r². First we will do the radius first, 5x5=25, so we will do 3.14x25=78.5. So 78.5ft is the answer!
