Answer:

The radius is 18.3cm

Step-by-step explanation:

Given

[tex]V = 25500cm^3[/tex]

Required

The radius, r

The volume (V) of a sphere is:

[tex]V = \frac{4}{3}\pi r^3[/tex]

So, we have:

[tex]25500 = \frac{4}{3}\pi r^3[/tex]

Solve for r

[tex]\pi r^3 = 25500 * \frac{3}{4}[/tex]

[tex]\pi r^3 = 19125[/tex]

Divide by [tex]\pi[/tex]

[tex]r^3 = \frac{19125}{\pi }[/tex]

[tex]r^3 = \frac{19125}{3.14}[/tex]

[tex]r^3 = 6090.8[/tex]

Take cube roots

[tex]r = 18.3[/tex] -- approximated
