Question

The surface area of a sphere is 64n square inches. Which equation can be used to solve for the radius of the sphere?

Answer 1

Answer:

64n = 4nr2

Step-by-step explanation:

So the formula for the surface area of a sphere is A=4πr^2

Now A= 64n

(im assuming n is supposed to be pi)

so 64n=4πr^2

thus the last one would be correct (also assuming its supposed to be r^2)
