The arc of a circle is a portion of the circumference, or the curved boundary of the circle. How is the length of an arc calculated? The length of an arc is calculated by multiplying the measure of the angle in radians by the radius of the circle. What is the relationship...
Again, if we want an exact answer when working with π, we use π. We substitute a rounded form of π, such as 3.14, if we want to approximate a response. Also, r refers to the radius of the circle, which is the distance from the center to thecircumference of a circle. ...
This means that the line 𝐴𝐵 divides the circle into two semicircles. So we can apply one of our circle theorems, which is that the angle inscribed in a semicircle is 90 degrees, a right angle. The inscribed angle is the angle at the circumference, angle 𝐴𝐶𝐵, which is give...
