I attached solution, for help u can ask.
why we are dividing it by 6 in calculating the area of disc
why we are taking its ratio
we are dividing by 1/6 because the area of disc that is covered by triangle is 1/6*area for total disc.. 1/6 as one angle of triangle is 60so 360/60=6 that means 1/6th of the area of disc is covered by triangle..
and we are taking ratio to find the fraction
ok thanks mam...I am making u as best
thanks.
