A solid cylinder has a base radius of 7 cm and a height of 20 cm. (a) Calculate the total surface area of the cylinder. (b) Calculate the volume of the cylinder. (c) A cone is carved out from the top of the cylinder. The cone has the same base radius of 7 cm and a height of 12 cm. Calculate the volume of the remaining solid after the cone is removed. [Take π = 22/7]
