Question

A conical tent is 10m gh and the radius of its base is 24m.Find cost of canvas required to make the tent,if the cost of 1sqm canvas is Rs.70

Answer 1

Heya

Height of the tent = 10m

Radius=24m

Slant height =√(r²+h²)

=√(10²+24²)

=√676

=26m

Curved surface area of the tent = πrl

= 22/7 × 24 ×26

=1961.14m²

Cost of 1m² canvas = ₹70

Cost of 1961.14m² canvas = 1961.14×70 = ₹137279.8

Hope it helps
