This right over here this other arc length when our central angle was 10 degrees this had an arc length of 05 pi. It is longer than the straight line distance between its endpoints which would be a chord There is a shorthand way of writing the length of an arc. The radius is 5 5 inches so.
Multiply the area by 2.
Given Arc length 23 cm. So 360 degrees corresponds to an arc length C 2pR. In order to derive the formula to calculate the angle at the centre of the sector the formulae for the arc length and area of a sector can be rearranged so that we. Arc measure arc length radius s r a r c m e a s u r e a r c l e n g t h r a d i u s s r.
