Question

if the cirrcumference of a circle is equal to the area of a circle, find the radius of a circle​

Answer 1

Answer:

Step-by-step explanation:

The radius of circle be r

The circumference of circle is 2πr

The Radius of circle is πr  

2

 

⟹πr  

2

=2πr

⟹r=2

Answer 2

Step-by-step explanation:

Area of a circle = circumference of the circle.

or, π.r^2 = 2.π.r.

or, π.r^2 - 2.π.r = 0.

or, π.r.( r -2) = 0.

π is not equal to 0 , then either r = 0 (not valid).

or, r - 2 = 0. => r = 2 units. Answer.
