Question

What is the area of the base in the figure below

Answer 1

BBBBBBBBBBBBBBBBB

the answer is B

Answer 2

`A=9\pi\ square\ units`

Explanation:

we know that

The base of the cylinder is a circle

The area of the circle is equal to

`A=\pi r^(2)`

we have

`r=6/2=3\ units` ----> the radius is half the diameter

substitute

`A=\pi (3)^(2)`

`A=9\pi\ units^(2)`
