What is the area of a sector with a central angle of 3π5 radians and a diameter of 21.2 cm?
Use 3.14 for π and round your final answer to the nearest hundredth.
Enter your answer as a decimal in the box.
____ cm²
Area = 1/2 (diameter/2)^2* (theta in rads) =
1/2 ( 21.2 / 2)^2 (3 *3.14 / 5 ) =
1/2 ( 10.6)^2 * (3 *3.14 / 5) ≈ 105.84 cm^2
