December 9th Volume Practice

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where r is the radius.

Front

How do you calculate the volume of a cylinder?

Back

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

Front

What is the value of π (pi) used in calculations?

Back

Use 3.14 for π in calculations.

Front

What is the formula for the volume of a cone?

Back

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

Front

How do you find the radius if you know the diameter?

Back

Radius = Diameter / 2.

Front

What is the volume of a cylinder with a radius of 5 cm and a height of 10 cm?

Back

V = π(5)²(10) = 250π cm³ ≈ 785 cm³.

Front

What is the volume of a cone with a radius of 5 cm and a height of 14 cm?

Back

V = (1/3)π(5)²(14) = (1/3)(25)(14)π ≈ 73.3π cm³ ≈ 230.4 cm³.

Front

What is the volume of a sphere with a radius of 6 cm?

Back

V = (4/3)π(6)³ = 288π cm³ ≈ 904.3 cm³.

Front

What is the volume of a cylinder with a diameter of 9 cm and a height of 32 cm?

Back

V = π(4.5)²(32) = 648π cm³ ≈ 2036.4 cm³.

Front

What is the volume of a rectangular prism with dimensions 4 cm x 5 cm x 6 cm?

Back

V = length × width × height = 4 × 5 × 6 = 120 cm³.
