Question

find the measure of major are if minor are=199 ​

Answer 1

Answer:A circle has 360 degrees. The central angle that substends the arc also subtends the same degrees of the arc. Example: what would be the length of an ard that is determined by a 45 degree central angle. Since the central angle is 45 degrees place it over 360 and reduce. ;45/360 = 1/8. So the central angle make this 1/8 of the circumerence of the circle, If tthe raduys us 20 then the entire circumference is pi times the radius times 2 or 40 pi. 1/8 times the circumference so the arc length is 1/8 times 40 pi or 5 pi,
