Volume of Cylinders, Cones and Spheres

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where r is the radius.

Front

What is the volume of a cylinder?

Back

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

Front

What is the volume of a cone?

Back

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

Front

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

Back

Approximately 3.14.

Front

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

Back

Radius = Diameter / 2.

Front

What is the volume of a sphere with a radius of 4 inches?

Back

267.9 in³.

Front

What is the volume of a cylinder with a radius of 4.5 inches and a height of 32 inches?

Back

V = π(4.5)²(32) = 640.5π in³.

Front

What shape has a circular base and tapers to a point?

Back

Cone.

Front

What is the volume of a cone with a radius of 3 inches and a height of 9 inches?

Back

V = (1/3)π(3)²(9) = 27π in³.
