A special blend of coffee beans is going to be sold in cylindrical canisters whose dimensions always have a height that is two more inches than the radius. The table shows various volumes, v(r), for the given radii, r. Choose the function represented by the data. V(r) = 2πr2 v(r) = πr2 + 2r v(r) = πr3 + 2πr2 v(r) = πr3 + 2.

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
