Question

A Conical tent has a conical toh with dimensions as shown
in the figure Calculate the cost of canvas required to
make the tent, if the cost of canvas is ₹50 per sq.m​

Answer 1

Answer:

Step-by-step explanation:

First we need to find the slant height.

l = √r^2 + h^2

= √8^2 + 6^2

= 10 m

curved surface area of cone = π r l

= 22/7 x 8 x 10

= 251.4 m^2

Curved surface area of cylinder = 2 π r h

= 2 x 22/7 x 8 x 14

= 704 m^2

Total curved surface area = curved surface area of cone + curved surface area of cylinder.

= 251.4 + 704 = 955.4 m^2

Cost of 1 sq mtr of canvas is Rs 50

So cost of 955.4 sq mtr of canvas = 955.4 x 50 = Rs 47,770
