Solution: Given that the perimeter and area of the circle are numerically equal. Let's assume a circle of radius 'r'. Circumference of the circle = 2πr Area of circle = πr2 The circumference of the circle and the area of the circle are equal. Thus, we have 2πr = πr2 2 = r Therefore, the radius of the circle is 2 units. Hence, the correct answer is A. ☛ Check: NCERT Solutions for Class 10 Maths Chapter 12 Video Solution: NCERT Solutions Class 10 Maths Chapter 12 Exercise 12.1 Question 5 Summary: The radius of the circle is 2 units if the perimeter and the area of a circle are numerically equal. ☛ Related Questions: Math worksheets and |
