Area of ENTIRE circle = PI * radius^2
Area = 3.14159 * 3^2
Area = 28.2743338823 square inches

Yellow Area = Circle Area * (75 / 360) = 28.2743338823 * 0.2083333333
Yellow Area = 5.8904862245 square inches

Green Area = Circle Area * (285 / 360) = 28.2743338823 * 0.7916666667 Green Area = 22.3838476578

*****************************************************
Double Check
Yellow Area = 5.8904862245 PLUS
Green Area = 22.3838476578 =
TOTAL = 28.2743338823
