Find the surface area for a sphere with a radius of 10 feet. Round to the nearest whole number.

Answer 1

The surface area of a sphere is given by the formula: A = 4πr^2, where r is the radius of the sphere.

Plugging in the radius of 10 feet, we have:
A = 4π(10)^2
A = 4π(100)
A = 400π

Rounding to the nearest whole number, we have:
A ≈ 1257 square feet

Therefore, the surface area of a sphere with a radius of 10 feet is approximately 1257 square feet.
