The first step is to divide by four to both sides
Sector area = (central angle / 360) * PI * radius^2
sector area = (210 / 360) * PI * 2.3^2
sector area = (7 / 12) * PI * 5.29

</span>
<span>sector area = 9.7 square meters (rounded)

The probability would be

,
Simplify and turn into ratio.
0.159 : 1.
I am unsure what the full question was though.
Hope this helps.
