surface area of a rightcircular cylinder. The area of a right circular cylinder is given by the polynomial 2pierh^2 where h is the height and r is the radius of the base. Suppose that a beverage can has a height of 6.2 inches and a radius of 1.3 inches. Evaluate the polynomial when h=6.2 and r=1.3 to find the area of the can. Use 3.14 for pie. What is the surface area ? inches^2

  • huh ??? -

    I think the area of the sides (without top and bottom) is

    A = 2 pi r h

    (not h^2)

    A = 2 (3.14) (1.3)(6.2) = 50.6 in^2
