01What is a Cylinder?

  • A cylinder is a three-dimensional geometric shape with two circular bases and a curved surface connecting them.
  • The bases of a cylinder are congruent, meaning they have the same size and shape.
  • The height of a cylinder is the perpendicular distance between the two bases.
  • The radius of a cylinder is the distance from the center of a base to any point on the base's circumference.

02Volume Formula

  • The formula to calculate the volume of a cylinder is:
  • V = π * r^2 * h
  • Where:
  • V is the volume of the cylinder
  • π is a mathematical constant approximately equal to 3.14159
  • r is the radius of the cylinder's base
  • h is the height of the cylinder

03Step-by-Step Calculation

  • To calculate the volume of a cylinder, follow these steps:
  • Measure the radius (r) of the cylinder's base.
  • Measure the height (h) of the cylinder.
  • Square the radius by multiplying it by itself: r^2.
  • Multiply the squared radius (r^2) by the height (h).
  • Multiply the result by π (pi) to obtain the final volume (V).
  • Round the volume to the desired precision, if necessary.

04Example Calculation

  • Let's calculate the volume of a cylinder with the following dimensions:
  • Radius (r) = 2.5 units
  • Height (h) = 7 units
  • Using the volume formula:
  • V = π * r^2 * h
  • V = 3.14159 * (2.5^2) * 7
  • V ≈ 3.14159 * 6.25 * 7
  • V ≈ 3.14159 * 43.75
  • V ≈ 137.815
  • Therefore, the volume of the cylinder is approximately 137.815 cubic units.
