How to find the perimeter of a sector using arc length formula

Показать описание
👉 Learn how to solve problems with arc lengths. You will learn how to find the arc length of a sector, the angle of a sector, or the radius of a circle. An arc of a circle is the curve between a pair of points on the circumference of the circle. The angle of an arc is the angle subtended by the arc with a pair of radii of the circle at the center of the circle. The portion enclosed by an arc of a circle and a pair of radii of the circle is called a sector.

The relationship between the arc length (S), the radius (r), and the angle subtended by the arc at the center (theta), is given by the formula S = r(theta), when theta is in radians. And is given by ((theta)/360) x 2pi r, when theta is in degrees.

Probably one of the most useful videos I've watched on YouTube... This made so much more sense than when my teachers tried to show me

Hello! This was super helpful but in my class we have to sometimes leave it as an exact answer. Eg. pi symbol and then a number. I have no clue how to do this, can you please help?

But what if we are given the length of the arc and the Q and we are being askes to find the radius. How to solve that?
