Question

What is the volume of a sphere with a 9m radius ?

Answer 1

The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius of the sphere.

Substituting r = 9m into the formula, we get:

V = (4/3)π(9m)³
V = (4/3)π(729m³)
V = 3.14 x 2,197
V ≈ 7,728.86 cubic meters

Therefore, the volume of the sphere is approximately 7,728.86 cubic meters.

Answer 2

the volume of a sphere with a 9m radius is approximately 3053.63 cubic meters.

Explanation:

The formula for the volume of a sphere is:

V = (4/3)πr^3

where r is the radius of the sphere and π is a constant approximately equal to 3.14.

Substituting the given radius of 9m into the formula, we get:

V = (4/3)π(9^3)

V = (4/3)π(729)

V = 3053.63 cubic meters (rounded to two decimal places)

Therefore, the volume of a sphere with a 9m radius is approximately 3053.63 cubic meters.
