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

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)
