Question

from a solid right circular cylinder with height 15cm and radius 7cm a right circular cone of same height and same base is removed, find the volume of remaining solid

Answer 1

it's very simple just minus the volume of cone and cylinder and you get the remaining solid

Answer 2

Given=radius of cyl.=7cm

height of cyl.=15cm

volume of cylinder=Πr×r×h

=22/7×7×7×15

=2310cm squ.

therefore,volume of cone

1/3Π×r×r×h

720 cm squ.

hence,remaining solid is

vol.of cyl.-vol.of cone

2310-720

1590cm squ.(answers)
