t, by the last Problem. II. Find the area of the triangle formed by the chord of thesegment and the two radii through its extremities. Ill If the segment is greater than the semicircle, add the twoareas together; but if it is less, subtract them, and the result ineithei case, will be the area… … And, AD=^/APi+PDi=zy/T44-{-16 = 12,04911 then, arc ^B = 126491X8-8i=8S,7309. Arc ADB=25,7309 half radius = 10 area sector AD£C = 257,3090area 04£=192 AP= CP= area CAB = 1~92 65,309 = area of segment ADB 2. Find the area of the segmentAFB\ knowing the following lines,viz: .45 = 20.5; FP= 17.17;…
