Question

A sphere has a diameter of 14.5 inches.

What is the surface area of the sphere?

Please help me

Answer 1

≈ 660.5 in²

Explanation:

The surface area (A) of a sphere is calculated using the formula

A = 4πr² ← r is the radius

Given diameter = 14. 5 then radius = 7.25, thus

A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²
