They are; { }, A, B, C, AB, AC, BC, ABC
there is no question
c
the radius is about 14.47 ft
658=pi*r^2 Given
658=3.14*r^2 Substitution
209.55=r^2 Division property of equality
√209.55=√r^2 square root property of equality
1503 quarters
There are 4 quarters in 1 dollar, so we multiply this number by 4.
375.75 * 4 = 1503
