Find the circumference and the area of a circle with diameter

5yd
.
Use the value
3.14
for
π
, and do not round your answers. Be sure to include the correct units in your answers.

The circumference is correct, but the area is wrong.

Did you use 2.5 for the radius? Did you square it?

a=61.62

A = 3.14 * 2.5^2

A = 3.14 * 6.25
A = ?

thank you!

You're welcome.

C = pi * d

A = pi * r^2

Just plug in the numbers.

I'll be glad to check your answers.

c= 15.7yd

a= 31.4yd^2
