Question

A tent 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 10.8 m.Find the canvas required for the tent in square meters.

Answer 1

canvas area=cylinder part area+cone part area
=2pi.r.h+pi.r.l
here r=4.5m
h=4.8m
l=root{(4.5)^2+(6)^2}
put this and find answer
