Question

16) Find the area of a major sector of a circle of diameter 42 cm and central angle is 60°

Answer 1

of the circle
diameter = 42 cm
radius = 21 cm
angle of the major arc = 360-60=300 degree C
now
area of the major arc
=( 300/360 x 22/7 x 21 x 21) sq cm
= 1155 sq cm

Answer 2

diameter = 42 cm
radius = 21 cm
major arc = 360-60=300°

Major arc's area => ( 300/360 x 22/7 x 21 x 21) cm sq

= 1155 cm sq
