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 56.4 m, find
the total canvas used in making the tent. If the cost of canvas is rs 8 per m'. find the
total cost of canvas required in making the tent.Answer(9900m^2,rs 79200​

Answer 1

Answer:

Given, height of cylinder=3.3m

diameter =100m

so, radius= d÷2= 50m

l.s.a of vylinder=2×22÷7×50×3.3=1036.86

slant height=56.4

l.s.a of cone=22÷7×50×56.4=1815

t.s.a of circus tent=2851.86

per m'=8

per 2851.86m'=2851.86×8=rs22814.88

app rs22812.00

Answer 2

Answer:

Area = 9891 m², Cost = Rs. 79,128/-

Step-by-step explanation:

To 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/-
