Answer:
yes i can
BUT IT IS LONG IT CAN TAKE TIME
Step-by-step explanation:
AREA OF SEGMENT AYB=SECTOR'S AR OYAB-TRIANGLE AREA OAB
- AREA OF SECTOR =120/360×22/7×21×21=462CM^2
NOW M IS MID POINT OF AB AND ANGLE AOM=BOM=1/2×120=60 DEGREE
om =x cm
om/oa=cos 60
x/21=1/2
x=21/2(dont solve to decimal )
om =21/2
am/ao=sin60=root3/2
am=21root3/2
so,ab=2am =2×21root3/2=21root3cm
ar of triangle aob=1/2×ab×om=1/2×21root3×21/2cm^2
=441/4×root3 cm2
so area of segment BYA=(462-441/4×root 3)cm^2
hope it help you
that was a though que
have a good day
