According to the formula pi r squared, for a circle with a radius of one unit the area equals pi.
For a circle with a radius of two units the area equals four pi. Ans = 16 pi units squared
For a circle with a radius of three units the area is nine pi.
A = 25 pi units squared, 36 pi units squared, 49 pi units squared... to 100 pi units squared.
So try this... given the formula for circumference of a circle C = pi * d or C = 2 p* r
What are the circumferences for these circles
r = 1 unit
r = 2 units
r = 3 units
Now finish the pattern to r = 10 units...
