Web7 apr. 2024 · Notice that this question is asking you to find the length of an arc, so you will have to use the Arc Length Formula to solve it! Before you can use the Arc Length Formula, you will have to find the value of θ (the central angle that intercepts arc KL) and the length of the radius of circle P.. You know that θ = 120 since it is given that angle KPL equals … WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
