Welcome back Anantaram — been a while! Let's pick up where you left off. To find the curved surface area of the remaining part, we need to consider the surfaces exposed after the hemisphere and cone are cut. Step 1: Identify the dimensions of the original cylinder. The height of the cylinder is H = 31 cm. The base radius of the cylinder is R = 7 cm. Step 2: Calculate the dimensions and curved surface area of the hemisphere. A hemisphere of radius equal to the base radius of the cylinder is cut off from one end. Radius of hemisphere r_h = R = 7 cm. The curved surface area of the hemisphere is given by the formula $2 r_
