Question

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

O 64n=4nr
O 64n= 2nr3
O 64n= 2nr3
O 64n= 4nr2

Answer 1

64n = 4nr2

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)
