The volume is
m3.

Answer 1

Find the volume of a sphere with a radius of 9 cm. Leave your answer in terms of pi.(1 point)
The volume is
cm3.

Answer 2

The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere.

Using the given radius of 3 m and approximating π as 3.14, we can substitute these values into the formula:

V = (4/3) * 3.14 * 3^3
= (4/3) * 3.14 * 27
= 113.04 m^3

Rounding to the nearest hundredth, the volume of the sphere is 113.04 m^3.

Answer 3

The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere.

Using the given radius of 9 cm, we can substitute this value into the formula:

V = (4/3)π * 9^3
= (4/3)π * 729
= 3056π cm^3

Therefore, the volume of the sphere is 3056π cm^3.
