प्रश्न
A cylinder and a cone are of the same base radius and of same height. Find the ratio of the value of the cylinder to that of the cone.
उत्तर
Since, cylinder and a cone both are have same radius and height.
Therefore,
`V_1/V_2 = (pir^2 h)/(1/3 pir^2h)`
`V_1/V_2 = 1/1`
`V_1 /V_2 = 3/1`
`V_1 :V_2 = 3:1`
