Question

a tent is in the shape of cylinder surmounted by a conical top if the height and diameter of the cylinder part are 2.1 and 4 respectively and the slant height of the top is 2.8 find the area of the Canvas used for making the tent also find the cost of the Canvas of 10th @ rupees 500 per metre note that the base of the 10th will be covered with Canvas ​

Answer 1

Answer:

56.5 meter square and rs2825

Step-by-step explanation:

curved surface area of cone

=πrl

22/7*2.8*2

=17.5

curved surface area of cylinder

2πrh

=2*22/7*2*2.1

=26.4

area of the base

=πr*r

22/7*2*2

=12.5

so,

total surface area of ⛺=17.6+26.4+12.5=56.5 square metres

per meter square cost=56.4*500=rupees,2825
