Question

What is the surface area of the sphere shown below with a radius of 6?

Answer 1

452.39 units²

Explanation:

To get the surface area of a sphere, all you need is the radius. The formula for the surface area is:

V=4πr²

So all you need to do is plug in the values:

V = 4πr²

V = (4)(π)(6)²

V = 4π36

V = 452.39 units²

BUT WAIT! If your teacher set the value of π to 3.14, the answer would be 452.16 units².

Answer 2

452.16 units^2

Explanation:

Given

Radius = r= 6 units

The formula for finding the surface area of a sphere is:

`A = 4\pi r^2\\A= 4 * 3.14 * (6)^2\\A=12.56*36\\A = 452.16`

In the formula, π is taken as 3.14.

So, the surface area of the given sphere is 452.16 units^2 ..
