<h2>The first question I don't really know how to do, but the second one I do. The answer to the second question is 113.04. So what you do in order to get the area of a circle when you know the radius is by using the following formula: A=πr^2. In this case, you have a circle's radius of 6. You take 6 and square it, then multiply it by 3.14 and get 113.04.</h2>
Given that the concentration has been modeled by the formula: C(t)=50t/(t^2+25) where: t is time in hours. The concentration after 5 hours will be given by: t= 5 hours plugging the value in the equation we get: C(5)=(50(5))/(5^2+25) simplifying the above we get: C(5)=250/(50)=5 mg/dl
