Answer:
radius = 2
theta = 90°
Area of quadrant = πr²theta
360°
= 3.14×2×2×90°
360°
= 3.14
it's ishu here!!!
Hope it's correct and it may help you!!!

Given : A Quadrant of circle of radius 2
use π = 3.14
To Find : area of the shape.
Solution:
Area of circle = πr²
Area of sector = ( sector angle / 360° ) * πr²
r = 2
sector angle = 90°
Area of shape = ( 90/360) π(2)²
= (1/4) 4π
= π sq units
= 3.14 sq units
area of the shape is π or 3.14 sq units
