arc length formula

Lets get back to geometry today, i have arc length formula for you guys below. I have mentioned how important geometry is for us right . Now lets look at the formula below.

The arc length for a sector of a circle is given by the arc length formula S = r.θ

Here S - represents the arc length - represents the radius of the circle

θ - represents the angle in radians made by the arc at the centre of the circle

I will come back with some examples on this concept shortly. I want you guys to look at the math past papers and find out if there are some problems related to arc length and we will work on it....
