Question

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

Answer 1

Step-by-step explanation:

given

the height of the conical tent =10m

the radius of the conical tent =24m

slant height=√r²+h²

=√24²+10²

=√576+100

=√676

=26m

the latrel surface area of cone =πrl

=22/7×24×26

=1961.14286m²

given that 1m²=RS 70

=1961.14286×70

=137280rs
