100 * pi = pi * r^2
Pi cancels on both sides of the equation
So... 100= r^2
= radius is 10
56 = 2 x 2 x 2 x 732 = 2 x 2 x 2 x 2 x 2
GCF = 2 x 2 x 2 =8
Rewrite 56+32 as the product of the GCF and a sum:
56 + 32 = 8 (7+4)
The answer is 1 1/2 because if you divide 4 into 6 you get I need and a half or 1.5
