Answer:

<h2>R = 16 in</h2>

Step-by-step explanation:

The formula of a Surface Area of a sphere:

S.A.=4\pi R^2

R - radius

We have

S.A.=1024\pi\ in^2

Substitute:

4\pi R^2=1024\pi               <em>divide both sides by π</em>

4R^2=1024             <em>divide both sides by 4</em>

R^2=256\to R=\sqrt{256}\\\\R=16\ in
