Question

Guys how did they got 2pi over 3?? by the way, the question is to find the shaded area.​

Answer 1

Answer:

The angle subtended by the arc of the sector at the centre is 120°, now because 2π is 360°, clearly 120° is 2π/3.

So, by using the formula 1/2r^2 theta as the area of the sector we get,

Area = 1/2* 4^2*2π/3

Answer 2

Step-by-step explanation:
