Perimeter Area and Volume 1. If you do not know it you can find the side length s using the radius r and the cones height h. You can calculate area of a triangle easily from trigonometry.
The perimeter of a polygon or any other closed curve such as a circle is the distance around the outside.
Find out how to measure the area of rectilinear shapes by breaking them down into squares and rectangles. Similarly the volume of a cube is V LLL. In the future well return to these concepts and talk about how to calculate the area and volume of objects like circles triangles and spheres. So for a cube the ratio of surface area to volume is given by the ratio of these equations.
