Answer:
The radius would be 4.8
Step-by-step explanation:
The circumerfence of a circle can be found use the equation C=2r. So since we are given the circumerce we need to rearrange the eqaution to it looks like
=r. when we do this out we find that the radius equals 4.8.
The maxima of f(x) occur at its critical points, where f '(x) is zero or undefined. We're given f '(x) is continuous, so we only care about the first case. Looking at the plot, we see that f '(x) = 0 when x = -4, x = 0, and x = 5.
Notice that f '(x) ≥ 0 for all x in the interval [0, 5]. This means f(x) is strictly increasing, and so the absolute maximum of f(x) over [0, 5] occurs at x = 5.
By the fundamental theorem of calculus,
The definite integral corresponds to the area of a trapezoid with height 2 and "bases" of length 5 and 2, so
