Find the sector length or angle 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.

What class is this? I ask because most people are talking about algebra 2 and pre calc, but I'm learning this in geometry

[brianmclogan]

Pre-calculus students range from 10th to 12th grade in my class

[TheTenthTail]

What age group were the students you taught this to?

[lxne]

Im from the uk and im doing this at gcse, i can tell this is like college or uni in america and it pisses me off how that one girl keeps complaining

[scrublordross]

Very helpful and clear/easy to understand. Thank you!

[swethadethabrew]

THANK YOU, IT WAS VERY ACCOMMADATING...

[sanzherharsha]

Thank u for making me understand it clearly

[windex]

much better than my algebra 2 teacher to be honest

[c.u.z.o.n.e]

Mr Brian could you make some videos solving 0606 past papers

[benjamineyke]

Thank you so much I was really impressed by this video <3

I only have radius and area of triangle how to find angle of minor sector?

[wendyargyle]

In central pivot irrigation, a large irrigation pipe on wheels rotates around a center point. A farmer has a central pivot system with a radius of 380 meters. If water restrictions only allow her to water 140 thousand square meters a day, what angle should she set the system to cover?

Do you have a video to explain a problem like this?

[mauri]

thanks, it helped me, i was so confused about the radians, but i get it now

[sarahlatham]

the circle with the line through it the angle right?

[claveecl]

Damn u completely mind f*cked me, I thought u were using a piece of paper until I saw u walk up to the board😂😂

[dollsloverlou]

I can tell that's why the students don't understand that because you don't write down the formula
