Use the given information to find the area of the sector. Round to four decimal places. a sector of a circle has a central angle of 30° and a radius 8 cm.

Answer 1

the sector with a central angle is 1/12th of the circle

area = pi(8^2)(1/12)= 64pi/12=-6.7552

Answer 2

Area of a circle = pir^2 , and with radius 8 = pi(8)^2 = 64pi

area of a sector with angle 30 degrees = 1/12 of area of a circle = 64pi/12 = 16pi/3 = 16.7551 square centimeters

30 degrees = 360 degrees/12
