What is the formula for the volume of a frustum of a cone?
1/3 * π * h * (R² + r²)
1/3 * π * h * (R² + r² + Rr)
π * h * (R² + r² + Rr)
π * h * (R² + r²)
Forklaring
The formula for the volume of a frustum of a cone is 1/3 * π * h * (R² + r² + Rr), where h is the height, R is the larger radius, and r is the smaller radius.
