    Answer:

    volume of cuboid = volume of cylinder this find the radius

    Step-by-step explanation:

    1 ) Dimensions of the metal cuboid ,

    Length = l = 22 cm

    Breadth = b = 15 cm

    Height = h = 7.5 cm

    2 ) Height of the cylinder ( H ) = 14 cm

    Let radius of the cylunder base = r cm

    According to the problem given ,

    Metal Cuboid melted and cast into a cylinder.

    Therefore,

    Volume of the cylinder = volume of the metal cuboid

    Pi × r^2 × H = lbh

    22 / 7 × r^2 × 14 = 22 × 15 × 7.5

    22 × r^2 × 2 = 22 × 15 × 7.5

    r ^2 = ( 22 × 15 × 75 ) / ( 22 × 2 × 10 )

    r^2 = 225 / 4

    r ^2 = ( 15 /2 )^2

    r = 15 / 2 cm

    r = 7.5 cm

    Radius of the cylinder = r = 7.5 cm.
