Question

A circle has a diameter of 15 centimeters and a central angle EOG that measures 210°. What is the area of sector EOG? Use 3.14 for pi and round your answer to the nearest whole number.

Answer 1

area of the whole circle = 3.14 * 7.5^2

area of the sector = (3.14 * 7.5^2 * 210)  / 360
                             =  103 cn^2  to nearest whole number
