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

Amazing Now I don't have to worry about circular measure
OPQ is a sector of a circle, centre O and radius 9 cm. Find the perimeter of the sector. Give your answer in terms of . can you help me in this
DUDE I WISH I HAD A TEACHER LIKE THIS
"I'm sure that won't turn on. Oh it turned on " 😅. Good one SIR 👍
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?

Which class can I find this type of topics
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?
