A cone is a very common shape and a party hat is what a cone looks like also a traffic cone is also an example of a cone. A cone is a three dimensional object with a circular base that reduces in thickness from the flat surface to the apex or vertex.
The formulas related to a cone are not much and in this article, would guide you on how to calculate the volume and surface area of a cone.
How To Calculate The Volume Of A Cone
The Volume of a cone is one third the volume of a cylinder with the same base radius and height and the formula for calculating the volume of a cone is given by:
1/3 * Area of Circular base * height
The formula is given by 1/3 * πr2 h and we would solve a question below so that you would understand how it is used.
Volume Of A Cone Examples
Given a cone with a radius of 7m and height of 12m, calculate the volume of the cone
Using the formula 1/3 * πr2 h, the solution becomes 1/3 * 22/7 * 7 * 7 * 12 = 616m3
Surface Area Of A Cone
The formula for calculating the surface area of a cone is πr√r+h2+r2
