Question

If the perimeter and area a circle are numerically equal then the radius of the circle is
1 ) 2 units
2) π units
3) 4 units
4) 7 units ​

Answer 1

Answer:

The radius of the circle is   (1)  2 units

Step-by-step explanation:

Let the radius of the circle is r units.

Therefore perimeter of the circle is 2πr units and area is πr² units²

Therefore according to the question 2πr = πr²

                                                         ⇒ r² - 2r = 0

                                                         ⇒ r (r - 2) = 0

                                                         ⇒ (r - 2) = 0 [∵ r≠ 0]

                                                         ⇒ r = 2

∴The radius of the circle is 2 units
