Oatmeal is packaged in a right circular cylindrical container that has a radius of 7 centimeters and a height of 16 centimeters.
What is the surface area of this container in terms of pi?
Area of top and bottom: A=2%28pi%29%28r%5E2%29=2%28pi%29%287cm%29%5E2=2%28pi%2949cm%5E2=98%28pi%29cm%5E2
Area of sides=(circumference)(height)=%282r%28pi%29%29%2816cm%29=2%287cm%29%2816cm%29%28pi%29=224(pi)cm^2
Total area=area of ends+area of sides=98%28pi%29cm%5E2%2B224%28pi%29cm%5E2=322%28pi%29cm%5E2
ANSWER: The surface area of the container is 322%28pi%29cm%5E2
