Answer:
125.6
Explanation:
Area of a circle = πr^2
Area of circle 1 = 3.14 × 11 × 11
=379.94cm^2
Area of circle 2= 3.14 × 9 ×9
=254.64cm^2
Area of a shaded region
=379.94cm^2 - 254.64cm^2
=125.60cm^2

After collecting evidence that concludes that the current plan to manage the Alaska crab fishery makes it only a potentially renewable resource, m<span>ore research should be done into the reproductive behaviors of the different species. This solution tries to solve the problem at its roots. That is, if the management determines why there are fewer species based on their reproductive behaviors, certain changes can be made in order to create an environment that will enhance their reproduction. </span>
