Question

The radius if a sphere is 5 feet. Find the area

Answer 1

The surface area (A) of a sphere is A=4πr²

By inserting the value of the radius (r), the surface area is found

A=4πr² r=5
A=4π5²
= 4π(25)
= 100π
= 314ft²

The area is 314 ft²

Answer 2

I hope this helps you



Area of Sphere =4.pi.r^2


Area of Sphere =4.pi.5^2


Area of Sphere =100.pi


Area of Sphere =314
