## How to Calculate the Volume of a Cylinder ### Formula **V = π × r² × h** Where: - **V** = Volume - **π** ≈ 3.14159 - **r** = radius of the base - **h** = height ### Surface Area - **Lateral area** = 2πrh (the curved side) - **Total area** = 2πrh + 2πr² (sides + top + bottom)
计算示例
Find the volume of a cylinder with radius 4 and height 10.
- 01V = π × 4² × 10
- 02= π × 16 × 10
- 03= π × 160
- 04≈ 502.6548
常见问题
How do you find the volume of a cylinder?
Multiply the area of the circular base (πr²) by the height: V = πr²h.
What is the lateral surface area of a cylinder?
The lateral (side) surface area is the area of the curved surface: 2πrh. Imagine unrolling the side into a rectangle with width 2πr and height h.
