Question

The height of a tent is 9m it's Base diameter is 24m what is slant height. Find the cost of the canvas cloth required if it costs 14 per Sq.m

Answer 1

Diameter = 24 m
Radius = 12 m
Height = 9 m
Slant Height = l 
So, l²= r²+h²
      l²= 12²+9²
      l²= 144+81
      l² = 225
      l = √225
      l = 15
C.S.A of Cone = πrl
                        =22/7×12×15
                        =565.71 m²
Cost of tent = Area×Cost of 1 m²
                   =565.71×14
                   = 7919.94 Rs
