Answer 1

The surface are of a sphere is given by this equation:

$A=4 \pi r^{2}$

Given that we have a sphere with a surface area of 64π. Then, to solve the radio of the sphere we use this equation:

$64 \pi =4 \pi r^{2}$

Answer 2

Surface of a sphere: S=64π square inches

Equation of the Surface of a sphere:
S=4πr^2
Replacing S by 64π:
64π=4πr^2

Answer: Fourth option 64π = 4πr^2
