# If the area of a

Given:

Area of circle = 2 × Circumference of circle …… (i)

Let the radius of the circle be ‘r’.

Then, the area of the circle = πr2

and the circumference of the circle = 2πr

Using (i), we have

πr2 = 2 × 2πr

πr2 = 4πr

r = 4 cm

Diameter = 2 × 4

= 8 cm

Hence, the diameter of the circle is 8 cm.
