Question

In a circle of radius 10.5, the minor arc is one fifth of the major arc. Find the area of the sector corresponding to the major arc.

Answer 1

radius of the circle r = 10.5 cm
and minor arc is one fifth of the major arc.
let the major arc subtend the angle  on the circumference.
therefore minor arc subtend angle (360 - ) on the circumference.
minor arc = 1/5* major arc

therefore the area of the sector corresponding to the major arc

hope this helps you.a
