What is the area of a sector with a central angle of 5π7 radians and a diameter of 5.6 in.?
Use 3.14 for π and round your final answer to the nearest hundredth.
What is the central angle? 5pi, 7pi, 35pi?
The central angle is 5pi over 7
Area of a sector = 1/2 x r^2 x Θ(in radians)
A =1/2 x (5.6/2)^2 x (5pi/7)
A = 19.6pi / 7
A =8.79 inches^2
