from a circular sheet of paper of radius 10 cm , a sector of area 40 % is removed. if the remaining part is used to make a conical surface then ratio of the radius and height of the cone is .....plz explain...

1) 1:2
2) 1:1
3) 3:4

Read Solution (Total 1)

slant height will be the asame radius of circular sheet, so l=10cm,
40% is removed so remaining area is 60%.
Total area is pi*10^2=100pi,
So 60% area is 60pi,
Now 60pi=pi*r*l
(l=10cm)
Therefor, r=6and l=10
by pythagoras, h=8
r:h=6"8=3:4
