Answer:
Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula
where r is radius of base of cylinder, h is the height
Volume of a cone is given by
where r is the radius of base of cone, h is the height
The radius of the cylinder = (diameter) =
(12) = 6cm
Height of cylinder = 15cm
Volume of cylinder
Radius of cone = (radius of cylinder) =
(6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone,
Difference is the volume of the remaining solid
