Find the area of a sector of the circle with the radius 4 cm and central angle 5pi/6

Question

Unsure how to fine the area of a sector with this given info

Answer 1

The area of a sector of a circle has a formula 1/2r^2*(Central angle)

So you have

r = 4

and central angle 5pi/6

1/2(16)(5pi/6) = (40/6)pi or (20/3)pi
