Answer:
301.6cm^2
Explanation:
3x+2x+x+90°=360(sum of shoes in circle equals 360°)
6x+90=360
6x=360-90
6x=270
divide both sides by 6
6x/6=270/6
x=45°
therefore 3x=3*45
=135
Area of the shaded sector
area of a sector =β(tita) /360*πr^2
=3x/360*πr^2
=3*45/360*πr^2
135/360*πr^2
Let π be 22/7
note r=16
0.375*22/7*(16)^2
0.375*22/7*256
0.375*3.143*256
ANS=301.728
The measurement closest is 301.6cm^2
