The volume of a cone is equal to one-third of the product area of circular base and height. Learn to derive its formula for a regular cone and see some solved examples at BYJU'S.
The slant-height formula r2+h2=l2 can be used to solve a missing slant for the types of right triangles found in the pyramids and cones shown in the diagrams included in this lesson. Let's take a look at an example. Slant Height of a Pyramid Formula (Slant Height of a Cone Formula...
Surface area of a cone = pi × r2 + pi × r ×( √(h2 + r2)) pi = 3.14 r is the radius h is the height l is the slant height of the cone Right square pyramid: Surface area of a pyramid = s2 + 2 × s × l s is the length of the base h is the height l is the...
The height (h) is the length from the center of the circular base to the apex and runs inside the cone. The slant height (l) is the length from the outside perimeter of the circular base to the apex, and it runs at an angle to the height. If looking at a cone in three ...

L is the slant height of the cone. The volume of the cone in terms of slant height can be given as V = (1/3)πr2h = (1/3)πr2√(L2- r2). Derivation of Volume of Cone Formula Here is an activity that shows how the formula for the volume of a cone is obtained from thevo...
The formulas for how to find surface area are: Sphere: SA = 4 * pi * r^2 where r = radius of sphere Cone: SA = pi * r^2 + pi * r * s where r = radius of sphere and s = slant height of cone Cube: SA = 6 * s^2 where s = length of one side of cube ...
