Question

A circus tent is cylindrical upto a height of 3.3 m and conical above it. If the diameter of the base is 100 m and slant height of the conical part is 56.4m,find the total canvas used in making the tent. If the cost of canvas is Rs.8 per sq.m ,find the total cost of canvas required in making the tent​

Answer 1

Answer:

Step-by-step explanation:

find the total canvas used to make the tent, we need to find the CSA of the tent.

Given, d = 100 m

So, r = 50 m

Cylindrical Part:

CSA = 2πrh

       = πdh

       = 3.14 x 100 x 3.3

       = 1036.2 m²   ...(i)

Conical Part:

CSA = πrl

       = 3.14 x 50 x 56.4

       = 8854.8 m²   ...(ii)

(i) + (ii)

= 1036.2 m² + 8854.8 m²

= 9891 m²

Cost = 9891 x 8 = Rs. 79,128/-
