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.

My teacher never even explained this in our lecture, yet it was a problem on the homework, thank you sm for this

[@timeless3118]

I learning this in grade 7

[@rayj6677]

Same

[@princesskadi7]

same and i hate math so fucking much it’s acc so useless to me especially this topic i could care less abt the area of the sector

[@levayy1218]

Yo .?

[@hyacinthokafor8232]

@@princesskadi7 Chill dude

[@prince_dbz_2123]

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

[@mad8671]

just do 10/360 times circumference its honestly not as complicated as this guys making it

[@brianmclogan]

True

DUDE I WISH I HAD A TEACHER LIKE THIS

[@brownlivesmatter8368]

thank you very much. now i know how to assemble an AR-15

[@IndependentZeeshan]

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

[@amnashah1210]

Thanks it helped me with my homework

[@frostingbeast4478]

Amazing Now I don't have to worry about circular measure

[@Factbaby23]

"I'm sure that won't turn on. Oh it turned on " 😅. Good one SIR 👍

[@UNKNOWN-qb4fw]

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?

[@s_2098]

Rearrange the equation.

[@Habib-py7yn]

Why did he divide by 180 and not 360

[@rnosquad7164]

Habib 123 because 1 pie equals 180 and 2 pie 🥧equals 360

[@kukundamuvavarirwa725]

Lovely stuff right there keep it up

[@4R20N1C]

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?

[@miaadrian5687]

THANK YOU SO MUCH, this helped me a lot!!

[@BigRed28]

Thanks for your help sir

[@santoshksingh21]
