what is the formula of finding length. In the video lesson we learned two equations that can be used to find the length L of a chord of a circle L 2rsintheta2 where r is the radius of the circle and theta is the angle. A L W.
In this lesson you will learn how to determine the missing length of a rectangle by applying the perimeter formula for a rectangle. The area of a rectangle A is related to the length L and width W of its sides by the following relationship. In the video lesson we learned two equations that can be used to find the length L of a chord of a circle L 2rsintheta2 where r is the radius of the circle and theta is the angle.
