Volume - spheres, cones, pyramids

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 cone?

Back

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

Front

What is the volume formula for a pyramid?

Back

V = (1/3)Bh, where B is the area of the base and h is the height.

Front

If a sphere has a radius of 5 inches, what is its volume using π = 3.14?

Back

V = (4/3) * 3.14 * (5)³ = 523.33 in³.

Front

What is the diameter of a sphere if its radius is 7 inches?

Back

Diameter = 2 * radius = 14 inches.

Front

How do you find 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 sphere with a radius of 11 inches?

Back

V = (4/3) * π * (11)³ = 5,575 in³.

Front

If a cone has a radius of 3 inches and a height of 9 inches, what is its volume?

Back

V = (1/3)π(3)²(9) = 27π in³.

Front

What is the relationship between the radius and diameter of a sphere?

Back

The diameter is twice the radius.

Front

How do you convert the diameter of a sphere to radius?

Back

Radius = Diameter / 2.
