Answer:
3.50
Step-by-step explanation:
C = 2πr
or
C = πd
In this case we are using C = 2πr
22 = 2 x 3.14 x r
22 = 6.28 x r
22/6.28 = 6.28r/6.28
3.503184713375796178343949044585987261 = r
But estimated is 3.50
the smallest number is the lower bound and the largest number is the upper bound, your inequality would be
8.2 ≤ x ≤ 9.5, where x represents the volume of tennis balls.
