Step-by-step explanation:

Another way to rewrite without negative exponents is by using the inverse fraction.

B - 523cm^3

Step-by-step explanation:

Volume of a sphere is

V = 4/3 * π * r^3

V - volume of the sphere

π - 3.142

r - radius of the sphere

We are provided with

π - 3.142

r - 5

Inserting this values to solve for the volume

V = 4/3 * π * r^3

V = 4/3 * 3.142 * 5^3

V = 1.33 * 3.142 * 125

V = 523.67 cm ^3

To the nearest whole number

V = 524 cm ^3
