Acylindrical can has a volume of 2in^(3). express the surface area of the can as a function of its radius, r.

Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon, a decagon, a 30-gon, a 50-gon, and a 100-gon.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)
