Question

A cylindrical canister of external diameter 32 cm and with walls 1 cm thick is filled with water to a height of 50 cm in the canister. The water is then poured into a second cylindrical canister with external diameter 52 cm and with walls 1 cm thick. Assuming that the water does not overfill the canister, to what height does the water fill the second canister?

    Answer:

    [tex]\frac{1550}{51}[/tex] cm

    Step-by-step explanation:

    For the first cylindrical canister:

    Let D, R denotes the external diameter and external radius.

    Ler r denotes internal radius of the canister.

    Let H denotes the height upto which the cylindrical canister contains water.

    D = 32 cm

    R = D/2 =32/2 = 16 cm

    r = R – 1 = 16 – 1 = 15 cm

    H = 50 cm

    Volume of the first cylindrical canister = [tex]\pi \left ( R^2-r^2 \right )H=\pi\left ( 16^2-15^2 \right )50=\pi\left ( 256-225 \right )50=1550\pi\,\,cm^3[/tex]

    For the second cylinderical canister:

    Let D’, R’ denotes the external diameter and external radius.

    Ler r’ denotes internal radius of the canister.

    Let x denotes the height of the second cylindrical canister.

    D’ = 52 cm

    R’ = D’/2 = 52/2 = 26 cm

    r’ = R’ – 1 = 26 – 1 = 25 cm

    Volume of the second cylinderical canister = [tex]\pi \left ( R’^2-r’^2 \right )H=\pi\left ( 26^2-25^2 \right )x=\pi\left ( 676-625 \right )x=51\pi\,x\,\,cm^3[/tex]

    Therefore,

    [tex]x=\frac{1550\pi}{51\pi}=\frac{1550}{51}[/tex]

    So,

    water fills the second canister to the height of [tex]\frac{1550}{51}[/tex] cm.
