Find Volume of 1 tennis ball:

Volume of 1 tennis ball = 4/3 x 3.14 x (2.5 ÷ 2)³

Volume of 1 tennis ball = 8.18 in³


Find Volume of 3 tennis balls:

Volume of 3 tennis balls = 8.18 x 3 = 24.54 in³


Find Volume of teh cylindrical canister:

Volume of the cylindrical canister = 3.14 x 1.5² x (2.5 x 3)

Volume of the cylindrical canister = 52.99 in³


Find unoccupied space:

Unoccupied space = 52.99 - 24.54

Unoccupied space = 28.45 in³


28.45 in³
