What is the formula for the volume of a sphere?

Back

V = (4/3)πr³

Front

What units are used to measure volume?

Back

Cubic units (e.g., cm³, in³, ft³) are used to measure volume.

Front

Which label would NOT be appropriate for volume?

Back

Front

What does the formula A=πr² represent?

Back

The area of a circle.

Front

How do you calculate the volume of a cone?

Back

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

Front

What is the volume of a sphere with a radius of 3 inches? Use 3.14 for pi.

Back

V = (4/3)π(3)³ = 113.04 in³.

Front

If the radius of a sphere is doubled, how does the volume change?

Back

The volume increases by a factor of 8.

Front

What is the volume of a sphere with a radius of 2 inches? Use 3.14 for pi.

Back

V = (4/3)π(2)³ = 33.51 in³.

Front

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

Back

The diameter is twice the radius (d = 2r).

Front

How do you find the volume of a cylinder?

Back

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