The radius is 5cm

Step-by-step explanation:

The surface area of a sphere is given by:

SA = 4\pi r^2

Here

Given

SA = 100π cm^2

Putting the values in the formula

100\pi = 4\pi r^2\\r^2 = \frac{100\pi}{4\pi}\\r^2 = 25

Taking square root on both sides

\sqrt{r^2} = \sqrt{25}\\r = 5 cm

The radius is 5cm

Keywords: Surface area, Radius
