Answer:
C. π(5²)13 + 1/3π(5²)12 cubic units
Explanation:
The composite figure is made up of a cylinder and a cone.
The volume of the composite figure = volume of the cylinder + volume of the cone
For the CYLINDER:
Volume = πr²h
h = height of the cylinder = 13units
r = radius of the cylinder = 5units
Volume = π(5²)13 cubic units
For the CONE:
Volume of a cone = 1/3πr²h
height of the cone = 25-13 = 12units
Radius of the cone = radius of the cylinder = 5units
Volume = 1/3π(5²)12 cubic units
Volume of the composite figure will give: π(5²)13 + 1/3π(5²)12 cubic units
