Answer:
the area of the circle is 4π
Step-by-step 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
