Question

In a circle of radius 10.5 cm minor arc is 1/5th of major arc . Find area of sector corresponding to major arc

Answer 1

minor arc=1/5 of major arc

by applying ar of the arc for the minor arc

teta/360*2*22/7*10.5

since the minor arc is 5 times th majorthe angle is

360/5=72

substituting this in formulae

we get

13.2cm

now find circumfrence of the circle 2*pie*r

2*22/7*10.5=66cm

now since minor arc is 13.2 and cis 66

therefor major arc is 66-13.2=52.8

Answer 2

Answer:- Area of sector corresponding to the major arc is 288.75 square cm.
