Question

Not sure on how to do this. Come really use some help.

Answer 1

Given:

SA = 2,461.76 cm²

The surface area of a sphere is given by:

$SA=4πr^2$

Hence:

$2,461.76=4\times3.14\times r^2$

Solving for r:

$r=\sqrt{\frac{2,461.76}{4\times3.14}}=14$

ANSWER

The radius of the sphere is about 14 cm
