Asked by Austin

What is the area and circumference of a circle with a radius of 3in.
Answered by Willow
Like I said with awl, I found the circumference forumla, which is:

c = pi times diameter
OR
c = 2 times pi times radius

I can't find the area formula. :(

Just place in 3 where I said "radius."

Hope I helped! :)

Area = pi * radius squared

A = pi*r^2
A = 3.14 * 9
A = 28.26 square inches
