Question

a cylinder and a cone have base radii 5 cm and 3 cm respectively
and their respective height are 4 cm and 8 cm find the ratio of
their volumes

Priya Sharma · Answer

vol cyl=pie into r into r into h
=22/7 x 5 x 5 x 4
=22 x 100 whole divided by 7
=2200/7 (1)
vol cone=1/3 x pie r x r x h
=1/3 x 22/7 x 3 x 3 x 8
=528/7 (2)
from (1) and (2)
2200/7 whole divide by 528/7
=25:66
dunno wthr d ans is ra8 lol
