Answer 1

the area of the circle is 4π

Explanation:

The computation of the area of the circle is shown below:

As we know that

The area of the circle = πr^2

where

diameter = 4

So radius = diameter ÷ 2

= 4 ÷ 2

= 2

Now the area of the circle is

= π × 2^2

= 4π

hence, the area of the circle is 4π
