Question

A tent is in the form of a cylinder of diameter 4.2 m and height 8 m surmounted
by a
cone of equal base and height 6 m. Find the volume of the air in the tent.
​

Answer 1

Answer:

u need to cinchor more then it seemed to be haven akns

Answer 2

The amount of canvas used to make the tent = Curved surface area of cylindrical part + Curved surface area of the conical part.

Curved Surface Area of a Cylinder of Radius R and height h

=2πRh

Radius of the cylindrical part =

2

Diameter

=4m

Curved surface area of a cone =πrl, where r is the radius of the cone and l is the slant height.

Radius of the conical part =

2

Diameter

=4m

For a cone, l=

h

2

+r

2

, where h is the height

=

3

2

+4

2

l=5m

Hence, area of canvas =(2×π×4×2)+(π×4×5)=36πm
