A circular tent is cylindrical to a height of 3 meters and conical above it. If its diameter is 105 m and the slant height of conical portion is 53m, calculate the length of the canvas 5 m wide to make the required tent?
option
a) 973.5
b) 3894
c) 1800
d) 1947

• Surface Area of tent=2(pi)*r*h+(pi)*r*l=(22/7)*(105/2)(6+53)=9375
  so,l*b=9375
  or,l=9375/5=1947

• Surface area of the tent= surface area of the cylinder + surface area of the cone
  =2*pi*r*h+pi*r*l
  =2*(22/7)*(105/2)*3+(22/7)*(105/2)*53
  =9735 sq.m
  l*b=9735
  b=5m,
  l=9735/5
  l=1947m
