3. Math Question
What is the area of a sector with a central angle of 10π7 radians and a radius of 18.4 m?
Use 3.14 for π and round your final answer to the nearest hundredth.
Enter your answer as a decimal in the box.
Area of a circle = pi * r^2
Area = 3.14 * 18.4^2 = 1063.08 m^2
Now we are looking for a fraction of this total area 2 pi radians is the entire circle angle....
we need 10 pi / 7 ths of this:
10pi/7 / 2pi * 1063.08 = 759 . 34 m^2
