Q: If the perimeter and the area of a circle are numerically equal then find the radius of the circle?

Answer:

r=2

Step-by-step explanation:

Perimeter of circle = 2πr

Area of circle = πr²

According to the Question,

Perimeter of circle = Area of circle

2πr = πr²

or, 2πr / πr = r

or, 2 = r

or, r = 2

Hence the radius is 2.
