Question

If a circle of radius 7 cm is divided into 10 equal parts, then the area of each sector is...?

Answer 1

Answer:

15.4 cm^2

Step-by-step explanation:

area of a circle = pi r^2

                         = 22/7 * 7 * 7

                        = 22 * 7

                       = 154 cm^2

area/ 10 parts = 154/10

                       = 15.4 cm^2

therefore, area of each sector is 15.4 cm^2
