The volume difference between a cylinder and a cone is 50.24 & sup3;, if the bottom radius of the cylinder is 2cm, the side area of the cylinder is Centimeter?
V cylinder = 3V cone
Vcylinder-vcylinder = 2vcylinder = 50.24 cm3
V cone = 50.24 / 2 = 25.12 CC
Vcylinder = 3vcylinder = 25.12 × 3 = 75.36 cm3
Vcylinder = 3.14 × 2 × 2 × H = 75.36 cm3
H = 75.36 / 12.56 = 6cm
The side area of the cylinder is 3.14 × 2 × 2 × 6 = 75.36 square centimeter
What kind of figure is a cylinder with equal base and equal height and a cone?
Taper
The radius of the bottom of a cylinder is 5cm and the height is 9cm. What is the side area of the cylinder? What is the volume of the cone with the same height as its bottom?

Side area 5 × 2 × 3.14 × 9 = 282.6 (square centimeter). Cone volume 5 × 5 × 3.14 × 9 × 1 / 3 = 235.5 (cubic centimeter)
3 × 3 × 3.14 × 5 × 1 / 3 = (CC)
2 = 0.25 (CM) 0.25 × 0.25 × 3.14 × 2 = (do it yourself),
28.26 ﹣ 3.14 ﹣ 2 = 4.5 (m) 4.5 × 4.5 × 3.14 × 3.1 / 3 = calculate by yourself (m ﹣ 179;),
2826 △ 3 = 0.942 (square centimeter),
6 △ 2 = 3 (decimeter) 3 × 3 × 3.14 × 6 × 1 / 3 = you can calculate it by yourself and look again
The diameter of the cone bottom is 6 decimeters, the height is 6 decimeters, and the side area, surface area and volume are calculated
Lateral area: 6 × 3.14 = 18.84 (DM)
18.84×6=113.04（dm²)
Surface area: 3.14 × (6 △ 2) &# 178; × 2 + 113.04 = 169.56 (DM & # 178;)
Volume: 3.14 × (6 ÷ 2) &# 178; × 6 = 169.56 (DM & # 179;)
