Question

How do you find the surface area of the sphere in terms `pi` given `S=4pir^2` and r= 8ft?

Answer 1

The surface area of the sphere is `256pi` square feet.

Explanation:

With the formula we can calculate the Surface Area.

`S=4pir^2`

We know the radius (`r`) to be `8ft`.

`S=4xxpixx8^2`

`S=4xxpixx64`

`S=256pi`
