Today we used the formulas we learned yesterday to determine the surface area of a given cylinder. Carson recalled how to find the formula for surface area of a cylinder. He remembered the area of a circle is A=pi(r^2). Then we considered the base of the cylinder. Carosn needed a reminder how he could come up with the area of the base. We recalled the top of the base is actually the circumference of the circle (pi*D). And the height of the cylinder was h. So he recalled the area of the base is 2PiR*h.
