Question

Cone hemisphere and cylinder in volume radius and height are equal find its rao

Answer 1

for cone-
V = 1/3 × π×r^2×h

for hemisphere-
V = 2/3×π×r^3

for cylinder-
V = π×r^2×h

ratio = cone: hemisphere: cylinder
= h: 2r: 3h

Answer 2

Hola!!

Here's your answer:

Given:
Cone, hemisphere and cylinder have equal height and radius
Therefore r = h

To find:
Ratio of volume of cone, cylinder and hemisphere

Solution:

Volume of cone : volume of cylinder : volume of hemisphere

1/3πr^2h : πr^2h : 2/3πr^2h

1/3πr^2×r : πr^2×r : 2/3πr^2×r ( putting r in the place of h because r = h)

1/3πr^3 : πr^3 : 2/3πr^3

1/3 : 1 : 2/3 ( πr^3 gets cancelled)

1/3 ×3 : 1 ×3 : 2/3 ×3 ( as ratio cannot be in fractions it is necessary to multiply by 3)

1 : 3 : 2

hope this helps ☺️
