I think it’s the second option
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2
It would be 40.
60 minus 20 = 40
Difference means subtraction
Answer:
Area = pi X r^2 = pi x (1)^2 = 3.14 x 1 = 3.14
