Question

Part c: If the surface area is 325 square inches, then what is the rardius r? In other words, evaluate r (325). Round your answer to 2 decimal places.​

Answer 1

To find the radius r of a sphere with a given surface area A, we can use the formula:

A=4πr2

Solving for r, we get:

r=4πA​​

Plugging in A = 325, we get:

r(325)=4π325​​≈5.11

So the radius r is about 5.11 inches when the surface area is 325 square inches.
