# How to find the area of a circle with circumference?

We use the formula, circumference of a circle (C) = 2πr and the area of a circle(A) = πr², where r denotes the radius of the circle

## Answer: The area of a circle = C²/4π where 'C' is the circumference of the circle

Let us see how we arrive at this equation

**Explanation:**

C = 2πr

⇒ C² = 4π²r²

⇒ C² = πr² × 4π = 4π × (A)

⇒ Area of the circle (A) = C²/4π
