Answer:

10 in

Step-by-step explanation:

So we want to consider the surface area of this sphere.

The formula for surface area of a sphere is $A=4 \pi r^2$ .

So we have that the surface area is $100 \pi$ .

So I'm going to replace $A$ in $A=4 \pi r^2$ with $100 \pi$ .

$100\pi=4\pi r^2$

Now our main objective here is to solve for $r$ :

Divide both sides by $4 \pi$ :

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

This gets us $r^2$ by itself:

$25=r^2$

What number squared gives you 25? If you don't know, just take the square root of both sides giving you:

$\sqrt{25}=r$

Now you can just put $\sqrt{25}$ in your calculator. You should get 5.

5 is the radius

The diameter is twice the radius.

So 2(5) is 10, so the diameter is 10 in.
