Find the surface area of a sphere to the nearest square unit 2inches
arsen [322]

Answer:

The surface area of sphere having 2 inches radius is 50.24 inches²

Step-by-step explanation:

  Given : radius of sphere = 2 inches

We have to find the surface area of the sphere

Surface area of sphere is given by :

A=4\pi r^2

Given radius of sphere is 2 inches

Thus, Surface area of sphere having radius 2 inches is

\Rightarrow A=4\pi (2)^2

Solving, we get,

\Rightarrow A=4\pi 4

\Rightarrow A=16\pi

Using \pi=3.14 , we get

\Rightarrow A=16\times 3.14

\Rightarrow A=50.24

Thus, the surface area of sphere having 2 inches radius is 50.24 inches²
