The diameter of a sphere measures 10.4 inches. what is the surface area of the sphere?
1 answer:
Area of the sphere ≅ 339.62 in².
<h3>What is Sphere?</h3>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
diameter d = 2r
Given that,
diameter d = 10.4 , r =5.2 in
then, Area of sphere = 4
= 4×3.14×5.2×5.2
≅ 339.62 in²
