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.
