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)

    • हल किया गया उदाहरण

    Find the volume of a cylinder with radius 4 and height 10.

    1. V = π × 4² × 10
    2. = π × 16 × 10
    3. = π × 160
    4. ≈ 502.6548
