In need of a math !
a cylindrical canister contains 3 tennis balls. its height is 7 inches, and its radius is 1.5 inches. the diameter of one tennis ball is 2.25 inches. 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.

31.58 in3
3 49.46 in3
3 5.96 in3
3 17.88 in3

Step-by-step explanation:

Given: The diameter of tennis ball = 2.25 inches

The radius of ball =

The volume of ball (sphere) is given by :-

For cylindrical canister, Height = 7 inches

Radius = 1.5 inches

The volume of  cylindrical canister (cylinder) is given by :-

Now, the canister’s volume is unoccupied by tennis balls

= Volume of canister - volume of 3 balls

=

Hence, the canister’s volume is unoccupied by tennis balls=

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
