Question

if the perimeter and area of the circle are numerically equal then the radius of the circle is is ​

Answer 1

Answer:

• The perimeter of a circle is 2πr where r is the radius of the circle. Therefore, if r is 2units then the area and perimeter of the circle would be numerically equal.

Answer 2

Answer:

2 units.

Step-by-step explanation:

Perimeter of circle = 2πr

Area of circle = πr²

ATP:

• Perimeter = Area

2πr = πr² (r gets cancelled)

2π = πr (π gets cancelled)

2 = r

∴ Radius of the circle when the perimeter and the area of circle are numerically equal is 2 units.
