Question

a circle has a circumference of 12 it has an are of length 11 what is the central angle of the arc in degrees

Answer 1

Given Circumference=12 units.
Arc =11units.

Angle subtended at centre=arc/radius

(this is lengthy and Involves big decimal.. So lets look at another method↓)

Again.. In a More Discrete way...

If we Divide the arc By circumference and multiply this with 360 We will get the answer.

i.e angle subtended=11×360/12=11×30=330°

hence 330° is the answer..

Hope it helps..
