Question

A cylinder is closed at both the ends by 18 cm high
cones. The radius of the cylinder is 7 cm and
the total height of the solid is 64 cm Find
the volume of this solid​

Answer 1

hey mate

here is the answer...

Answer:

height of the cylinder(H)=64 cm-2*18cm

=64 cm-36 cm

=28 cm

volume of the solid=volume of the cylinder+2*volume of the cone

volume of the solid=πr²H+2*1/3πr²h

volume of the solid=πr²(H+2/3h)

volume of the solid=π(7)²(28+2/3*18)

volume of the solid=22*7(28+12)

volume of the solid=22*7*40

volume of the solid=6160 cm³(Answer)

Answer 2

Answer:

6160cm3 is the answer of your question...
