Answer:

Step-by-step explanation:

45:2

Volume of cylinder : Volume of cone

kritika10089: pls explain how

sonumandal1812: The formula for both was to be put in ratio

sonumandal1812: πr1^2h1:1/3πr2^2h2

sonumandal1812: Both the π got cut and the values of r1,h1,r2,h2 were put in the equation.

sonumandal1812: r1= radius of cyclinder h2= height of cylinder r2= radius of cone and h2= height of cone
