btw its not a thong soo no ideas!!

Lol @ thongs.

5. Hashir

yup i m here

6. Hashir

apply sine rule a=1/2(6)(6)sin60 then

7. saifoo.khan

aera of triangle = 7.8

8. Hashir

find area of sector A of sector= (60/360)(pie)(3)^2 multiply it by three

9. Hashir

subrat it from the A u get from the sine rule

10. saifoo.khan

lol, im getting 3 different answers!

11. Hashir

apply sine rule a=1/2(6)(6)sin60 then find area of sector A of sector= (60/360)(pie)(3)^2 multiply it by three ans=15.58-3(4.71)=1.443

hey hello saif

13. saifoo.khan

lol, hi honey.. supp?

nm u?

15. saifoo.khan

same here, nm.

hi..........saif i solved the question koi medal to do

Looks like 3 sectors of a circle. Area of a sector of a circle is: area of circle * degrees of sector/360 the sector has 60 degrees because the triangle is equilateral. Area of circle = 9π Area of 3 sectors: 9π * 60/360 * 3 = 4.5π Area of shaded part = area of triangle - 4.5π area of triangle = 1/2(6)(6)(sin 60) = 15.5884573 4.5π = 14.1371669 15.5884573 - 14.1371669 = 1.4512904 Hope that helps
