The methid for area of a sector is find the fraction (angle required)/(360) x ( area of full circle) Or if in radians (angle)/2 x r^2 because the pi parts cancel. ( a ) A = 71/360 x pi x...

sector area = pir^2*(central angle/360) if angle is in degrees =pir^2*(central angle/2pi) if angle is in radians area = pi 16^2 (240/360) = 256(2/3)pi = 512pi/3
