You add 2 to 8 to get 10. I decided on that because that's just what you do for simple addition. ;)
To find the circumference you use c = pi d. Radius * 2 = Diameter
c = 3.14(36)
c = 113.04 in. square.
Let's say the original radius was "r", so the circumference is 2πr and the area is πr².
Now when you double the radius, the you get a new circle with radius 2r, circumference 2π(2r) = 4πr, and area π(2r)² = 4πr².
