8th Grade Volume Review

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

Calculate the volume of a cylinder with a height of 9 cm and a radius of 4 cm.

Back

144π cm³

Front

What is the volume of a cylinder with a diameter of 5 feet and a length of 9 feet? (Use π = 3.14)

Back

88.3 ft³

Front

What is the formula for the volume of a sphere?

Back

Volume = (4/3)πr³, where r is the radius.

Front

Calculate the volume of a sphere with a radius of 6 ft.

Back

904.32 ft³

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3)πr²h, where r is the radius and h is the height.

Front

Calculate the volume of a cone with a height of 4 in and a radius of 6 in.

Back

48π in³

Front

What is the value of π used in volume calculations?

Back

Approximately 3.14 or 22/7.

Front

How does the volume of a cylinder change if the height is doubled?

Back

The volume doubles, since volume is directly proportional to height.

Front

If the radius of a cylinder is halved, how does the volume change?

Back

The volume decreases to one-fourth, since volume is proportional to the square of the radius.
