# What is the area of a circle with a radius of 4 units?

The area of a circle is the amount of space enclosed within the boundary of a circle.

## Answer: The area of the circle with a radius of 4 units is 16π sq. units.

Let's find the area of the circle.

**Explanation:**

Area of a Circle = πr^{2 }= πd^{2}/4

- where
**r**is the radius of the circle - where
**d**is the diameter of the circle. - π is the constant whose value is approximately 22/7 or 3.14...

So, the area of circle = πr^{2}

Given that radius of the circle is 4 units.

Then the area of circle = πr^{2} = π(4)^{2} = 16π square units.
