Some racquet balls are sold in cylindrical cans of three balls. Each ball has a diameter of 2.25 inches. The can has a diameter
kicyunya [14]

Volume of 1 ball = 4/3 π r³ = 4/3 (3.14) (2.25 ÷ 2)³ = 5.961 in³


Volume of 3 balls = 5.961 x 3 = 17.883 in³


Volume of cylinder = πr²h = (3.14) (2.25 ÷ 2)² (6.75) = 26.825 in³


Empty Space = 26.825 - 17.883 = 8.94 in³ (nearest hundredth)


Answer: 8.94 in³

Eight is added to a number and the sum is doubled, the result is -11 less than the number. Find
inna [77]
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:

(x + 8) x 2 = x - 11

Then, solve:

2x + 16 = x - 11

2x = x -27

x = -27

This can then be checked by using the number in the original text.

-27 + 8 = -19

-19 x 2 = -38

-38 is 11 less than -27.

Hope this helps :)
