Cone area

The first step in determining the surface area of ​​a cone is to measure the radius of the circle, part of the cone. Next, you need to find the area of ​​a circle, or base. As you know, the area of ​​a circle is 3.14 times the square radius (nr2). Now you will need to find the area of ​​the cone itself. To do this, it is necessary to measure the side (tilt height) of the cone.
