Question 1: lateral area is CH (you know what C is and what H is), so the circumference of the cylinder bottom is 12 and the height is 12, so lateral area is12 ×12 =144 (. )

Question 2: According to the question, the height of this cylinder is 10cm, and the diameter of the bottom is 10cm, so the area of the bottom is 5× 5× 3. 14 = 78.5 cm? So the bottom area times the height is higher than 785cm? (This is the answer)
