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
