Question

A rightcylindrical can

is to hold approximately 1 L of water. What shouldbe the height of
the can if the radius is 12 cm?

Answer 1

Answer: The height of the cylindrical can is 2.21 cm

Explanation:

The equation used to calculate the volume of cylinder is:

`V=\pi r^2h`

where,

V = volume of right cylindrical can =
`1L=1000cm^3` (Conversion factor:
`1L=1000cm^3` )

r = radius of the can = 12 cm

h = height of the can = ?

Putting values in above equation, we get:

`1000cm^3=(3.14)* (12)^2* h\\\\h=(1000)/(3.14* 12* 12)=2.21cm`

Hence, the height of the cylindrical can is 2.21 cm
