Cone Formulas

Slant Height:l = sqrt(r^2 + h^2)
Volume:V = (1/3) x pi x r^2 x h
Lateral Area:A_l = pi x r x l
Total Area:A = pi x r x (r + l)

Step-by-Step Calculation

Given: r = 5, h = 10

Slant height: l = sqrt(5^2 + 10^2) = 11.1803

Volume: V = (1/3) x pi x 5^2 x 10 = 261.7994

About Cones

Definition

A cone is a three-dimensional geometric shape that tapers smoothly from a circular base to a point called the apex or vertex.
