Answer:
Step-by-step explanation:
Given:
From the given figure.
Cone height = 7 mm
Cylinder height = 5 mm
Base radius of the cylinder = base radius of the cone = 3 mm
The volume of the given figure is
Volume = volume of cylinder + volume of cone-----------(1)
The volume cylinder is.
----------(2)
Where: r = radius of the cylinder, h = height of the cylinder.
Put the value of height and radius of the cylinder in equation 2.
The volume of the cylnder is
The volume cone is.
--------------(3)
Where: r = base radius of the cone, h = height of the cone.
Put the value of height and base radius of the cone in equation 3.
The volume of the cone is .
Put the value of the volume of cone and cylinder in equation 1.
Therefore, the volume of the given figure is
