The area of a quadrant of a cirlce is $\frac{\pi}{9}$ m². Its radius (in metres) is equal to:

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. $\frac{2}{3}$

A quadrant is nothing but 1/4 part of a circle so its area will also be 1/4 of the area of a circle.

Area of Quadrant = $\frac{\pi r^2}{4}$ = $\frac{\pi}{9}$

r² = 4/9

r = 2/3.
