Answer:

the radius would have to be 3 for both the volume and the surface area to be the same

Step-by-step explanation:

The radius of the sphere will be 3 units.

We have a sphere whose surface area is equal to its volume.

We have to find the radius of this sphere.

What is the formula to calculate the surface area and volume of a sphere with radius ' r ' ?

The formula to calculate the surface area and volume of a sphere is -

S.A. -  4π[tex]r^{2}[/tex]

Volume -  [tex]\frac{4}{3} \pi r^{3}[/tex]

According to the question -

The surface area of sphere is equal to its volume.

Therefore -

4π[tex]r^{2}[/tex] = [tex]\frac{4}{3} \pi r^{3}[/tex]

4π[tex]r^{2}[/tex] = 4π[tex]r^{2}[/tex] x [tex]\frac{r}{3}[/tex]

[tex]\frac{r}{3}[/tex] = 1

r = 3 units

Hence, the radius of the sphere will be 3 units.
