Question

Radius of a circle is 10.5cm and angle of the sector is 45.find the area of the minor sector of the circle.[π=22\7]
​

Answer 1

Answer:

2480.625

Step-by-step explanation:

radius=10.5

angle of sector = 45

area of circle = π(10.5)^2

                      =110.25×22/7

area of part = (angle×area)/2π

                    =(45×110.25×22/7)/2π

                   = 2480.625
