Answer:

The formula for the surface area of a sphere is:

Surface Area = 4πr^2

where r is the radius of the sphere and π (pi) is a mathematical constant approximately equal to 3.14159.

In this case, we are given that the radius of the sphere is 13 inches. So we can plug in the value of r into the formula to find the surface area:

Surface Area = 4πr^2

Surface Area = 4π(13^2)

Surface Area = 4π(169)

Surface Area = 676π

Therefore, the surface area of the sphere is 676π square inches.
