Question

8. Atent is cylindrical to a height of 4.8 m. and conical above it. The radius of the base is
4.5m. and total height of the tent is 10.8m. Find the canvas required for the tent inste
meters.​

Answer 1

Step-by-step explanation:

ANSWER

Given a tent is cylindrical of height 4.8m and conical above and

the radius of the base is 4.5m and a total height of the tent is 10.8m

The radius of the conical =radius of cylinder=4.5m

The height of conical above = total height of tent-height of cylinder

=10.8−4.8=6m

And slant height =l=

(4.5)

+(6)

=

20.5+36

=

56.25

=7.5m

Then total canvas required =curved surface area of cone +curved surface area of the cylinder

=πrl+2πrh

=πr(l+2h)

=

×4.5(7.5+2×4.8)

=

22×4.5×17.1

=241.85m
