Question

] A conical tent is 5m high and the radius of its base is 12 m. Find:
i) Slant height of the tent
ii) The cost of the canvas required to make the tent. If the cost of 1 m canvas is Rs. 70​

Answer 1

Answer:

1.pythagoras theorem:hypo^2=radius^2+height ^2

slant height=12^2+5^2

=144+25

169=13^2

slant height =13 m

2.lateral surface area=22/7×r×l

=22/7×12×13

=490.28 sq.m

=>cost =70×490.28

=Rs.34319.6
