"A cylindrical canister contains 3 tennis balls. Its height is 8.75inches, and its radius is 1.5. The diameter of one tennis bal
l is 2.5. How much of the canister’s volume is unoccupied by tennis balls? Use 3.14 for π, and round your answer to the nearest hundredths place." 24.54in^3

---------------------------------------------- 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)
Its best to turn fractions into decimals so its easier to solve the problem, in order to do this you would divide the number on the top to the number on the bottom. Ex: 1 divide by 2 So the numerator divided by the denominator. The top of the faction is the numerator and the bottom of the faction is the denominator. So 1 divided by 2 = 0.5 you would replace 0.5 for the 1/2.
