Answer:
Step-by-step explanation:
Total area of canvas of one tent = CSA of cylinder+CSA of cone.
Radius of cylinder=r and radius of cone=r2
=πrh+πr2l.
=π(rh+r2l).
=π(2.1×4+2.1×2.8)
=π(8.20+5.88)
=π(14.08)
=(22/7)14.08
=44.25cm².
Area of 100 tents = 44.25×100.
= 4425cm².
Cost of 100 tents = 4425×100.
= Rs.442500
Association had to pay 50% of Rs.442500 = (50/100)×442500.
= (1/2)×442500.
= Rs.221250.
