HEY DEAR ... ✌️

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 θ on the circumference.
therefore minor arc subtend angle (360 - θ) on the circumference.
minor arc = 1/5* major arc
2πr*360-θ360=15*2πr*θ3605(360-θ)=θ1800-5θ=θ6θ=1800θ=18006=300
therefore the area of the sector corresponding to the major arc
=πr2*θ360=227*10.5*10.5*300360=33*10.5*56=288.75 cm2
