Question

A conical tent is 10m high and the radius of its base is 24m. Find the slant height of the tent. If the cost of 1m² canvas is Rs.70, find the cost of the canvas required to make the tent.

Answer 1

We have,

Radius of base of tent = r = 24m 

Vertical height = h = 10m 

∴slant height = l =\(\sqrt{r^2+h^2}\) 

= \(\sqrt{576+100}\) 

= 26m

∴ Cost of canvas required = 

Rs.\(\{(\frac{22}{7}\times24\times26)\times70\}\)

= Rs. 137280
