Volume of Cylinders, Cones and Spheres

Front

What is the formula for the volume of a cylinder?

Back

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

Front

What is the formula for the volume of a cone?

Back

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

Front

What is the formula for the volume of a sphere?

Back

V = (4/3)πr³, where V is volume and r is radius.

Front

Calculate the volume of a cylinder with height 25 in and radius 26 in using π = 3.14.

Back

V = πr²h = 3.14 * (26)² * 25 = 53,066 in³.

Front

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

Back

π is approximately 3.14.

Front

What does 'radius' refer to in a cylinder, cone, or sphere?

Back

The radius is the distance from the center of the base to the edge.

Front

What does 'height' refer to in a cylinder or cone?

Back

The height is the perpendicular distance from the base to the top.

Front

How do you find the volume of a cylinder?

Back

Multiply the area of the base (πr²) by the height (h).

Front

How do you find the volume of a cone?

Back

Multiply the area of the base (πr²) by the height (h) and divide by 3.

Front

How do you find the volume of a sphere?

Back

Use the formula V = (4/3)πr³.
