Questions Related to areas related to circles

Multiple choice maths areas related to circles area of a sector of a circle sector and arc of a circle area of sectors and segments

If the angle subtended by the arc of a sector at the center is $90$ degrees, then the area of the sector in square units is

  1. $2\pi r^2$
  2. $4\pi r^2$
  3. $\dfrac{\pi r^2}{4}$
  4. $\dfrac{\pi r^2}{2}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Since the Central angle is $90^{\circ}$, it means it is a Quad-circle.

So the Area of this sector is $\dfrac{1}{4}$ th of the Circle's Area $= \dfrac{1}{4}* \pi r^2$
