Question

If the sphere shown above has a radius of 20 units, then what is the approximate volume of the sphere? (Use 3.14 forPI .)

A. 41,866.67 cubic units
B. 16,746.67 cubic units
C. 33,493.33 cubic units
D. 628 cubic units

Answer 1

33,493.33 cubic units

Explanation:

We are given that a sphere has a radius of 20 units and we are to find the volume of this sphere.

We know the formula for the volume of a sphere:

Volume of a sphere =
`\frac{4} {3} \pi  r^3`

Substituting the given value of radius in the above formula:

Volume of sphere =
`(4)/(3)` ×
`3.14` ×
`20^3`

= 33,493.33 cubic units
