1.	2. A conical shaped circus tent of base radius 70 m and height24m. How much cloth required to construct this tent.
Answer» Given,Radius of cone r = 70 mHeight of cone h = 24 mLet slant height of be l Then,l^2 = r^2 + h^2l^2 = 7070 + 2424l^2 = 4900 + 576l^2 = 5476l = 74 m Curved surface area of cone= pirl= 22/77074= 220*74= 16280 m^2 Therefore, length of cloth required = 16280 m^2

2. A conical shaped circus tent of base radius 70 m and height24m. How much cloth required to construct this tent.

Answer»

Given,Radius of cone r = 70 mHeight of cone h = 24 mLet slant height of be l

Then,l^2 = r^2 + h^2l^2 = 70*70 + 24*24l^2 = 4900 + 576l^2 = 5476l = 74 m

Curved surface area of cone= pi*r*l= 22/7*70*74= 220*74= 16280 m^2

Therefore, length of cloth required = 16280 m^2
