If the numerical value of the circumference of a circle is equal to the numerical value of 1/11 of the area of the circle, then what is the numerical value of the radius of the circle?

If the numerical value of the circumference of a circle is equal to the numerical value of 1/11 of the area of the circle, then what is the numerical value of the radius of the circle? Correct Answer 22

Given:

Numerical value of the circumference of the circle is equal to the numerical value of 1/11 of the area of the circle.

Concept: /Formula:

Area of the circle = πr2

Perimeter of the circle = 2πr

Calculation:

According to the question

2πr = 1/11 × πr2

⇒ 2 = (1/11) × r

⇒ r = 11 × 2

⇒ r = 22

∴ Radius of the circle is 22.
