Our online Area of a Frustum of a Cone Calculator simplifies complex geometry calculations. Quickly determine the total and lateral surface area by inputting the large radius, small radius, and height. Understand the formula and get precise results instantly for engineering, design, or academic needs. Perfect for students and professionals alike.
Formula:
The total surface area (A) of a frustum of a cone is given by the formula:
A = π [ (R + r)√(h2 + (R - r)2) + R2 + r2 ]Where:
- R = Radius of the larger base
- r = Radius of the smaller base
- h = Height of the frustum
- π ≈ 3.14159
