I've tried this problem a few times, but I can never seem to get it right.
Can you show me step by step how to work it out?
The area of a circle is pi * r^2
so to find the radius us this formula:
r= sqrt( 25/pi)
The radius is about 2.82 in
The area of a circle is pi times r squared. So. If the area is 25 in squared, can you get from there what r is?
A = PI * r^2
25 = 3.14r^2
divide 3.14 to other side
7.96 = r^2
take square root
r = 2.82 in
