Question

The diameter of a sphere measures 10.4 inches. what is the surface area of the sphere?

Answer 1

Area of the sphere ≅ 339.62 in².

What is Sphere?

A sphere is a geometrical object in three-dimensional space that is the surface of a ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.

Area of sphere = 4$\pi r^{2}$

diameter d = 2r

Given that,

diameter d = 10.4 , r =5.2 in

then, Area of sphere =  4$\pi r^{2}$

                                   =   4×3.14×5.2×5.2                  

                                  ≅  339.62 in²
