<h3>Volume of the remaining solid = 628 cm^2</h3><h3>Whole surface area = 659.4 cm^2</h3>
Step-by-step explanation:
Now, Given that:-
Diameter (d) = 10 cm
So, Radius (r) = 10/2 = 5cm
Height of the cylinder = 12cm.
Radius of the cone = 5 cm.
Height of the cone = 12 cm.
Volume of the cone = 1/3 *πr^2h
therefore, the volume of the remaining solid
Curved surface of the cylinder =
therefore, The whole surface area of the remaining solid
= curved surface area of cylinder + curved surface area of cone + area of (upper) circular base of cylinder
