Radius of pentagon
WebIn such cases, the radius is the line drawn from the center of the polygon to one of its vertices. It is also referred to as the circumradius. The perimeter of this pentagon can be calculated after finding the side length with the help of the formula: Side length = 2r × Sin(180/n), where 'r' is the radius and 'n' represents the number of sides. WebStreet light post The post of a street light is shaped like a truncated cone, as shown in the picture below. It is a large cone minus a smaller top cone. The large cone is 30 feet tall with base radius 1 foot. The smaller cone is 10 feet tall with base radius of 0.5 feet. To the nearest tenth, (a) find the volume of the large cone.
