Question

If the diameter of a sphere is 2 meters, then what is its surface area? Leave your answer in terms of π π .

Answer 1

The surface area is
`SA=4\pi\ m^(2)`

Explanation:

we know that

The surface area of a sphere is equal to

`SA=4\pi r^(2)`

where

r is the radius of the sphere

we have

`r=2/2=1\ m` -----> the radius is half the diameter

substitute

`SA=4\pi (1)^(2)`

`SA=4\pi\ m^(2)`
