Question

A sphere has a surface area of 9,244 square feet.

What is the radius of the sphere? Round
to the nearest hundredth.​

Answer 1

The answer to your question is radius = 27.1 ft

Explanation:

Data

Surface area = 9244 ft²

radius = ?

Process

To solve this problem, look for the formula of surface area, substitute values and simplify.

1.- Formula of the area of a sphere

Surface area = 4π r²

2.- Solve for r²

r² = Surface area / 4π

3.- Substitution

r² = 9244 / 4(3.14)

4.- Simplification

r² = 9244/12.56

r² = 735.98

5.- Result

r = 27.1 ft
