A circus tent is made up using two different coloured cloth material. red coloured material is used to make cylindrical part upto a height of 3 m and green coloured material to make conical part above it. if the diameter of the base is 105 m and slant height of the conical part is 53 m, find the red coloured material and green coloured material required [assuming no stiching margins is required].

Curved Surface area of red cylindrical part = 2πrh
= 2x22/7x105/2x3
= 22x15x3
= 22x45 = 990m²
Curved Surface area of green conical part = πrl
= 22/7x105/2x53
= 22x15/2x53 = 8745m²
= 2x22/7x105/2x3
= 22x15x3
= 22x45 = 990m²
