Find the volume of a cylinder with a radius of 4 cm and a height of 8 cm. (use π=3.14).
From a solid cylinder whose height is 8 cm and radius 6 cm, a conical cavity of height 8 cm and of base radius 6 cm is hollowed out. Find the volume of the remaining solid. Also, find the total surface area of the remaining solid. [Take π=3.14.]
Question 4 (ii) If the lateral surface of a cylinder is 94.2cm2 and its height is 5 cm, then find:
(ii) its volume. [Use π=3.14]
