Question

a solid is in the form of a cone mounted on a right circular cylinder both having same radii as shown in the figure the radius of the base and the height of the cone are 7 cm and 9 CM respectively if the total height of the solid is 30 cm find the volume of the solid

Answer 1

Answer:

=3696cm^3

Step-by-step explanation:

Volume of the solid=Volume of cone+Volume of cylinder

Volume of cone=1/3πr^2h

=1/3x22/7x7x7x9

=462cm^3

Height of cylinder=Total height of solid-height of cone

=30-9

=21cm

Volume of cylinder=πr^2h

=22/7x7x7x21

=3234cm^3

Therefore, Volume of solid=462+3234

=3696cm^3
