Question 314647: A cylindrical water tank is to be painted. It has a radius of 8 feet and a height of 12 feet. Which of the following is the best approximation of the surface area of the tank? Answer by Jstrasner(112) (Show Source):
You can put this solution on YOUR website! Hey,
Well the formula for surface area of a cylinder is:
2πr^2 + 2πrh
So in this case, the surface area would be:
2π(8^2) + 2π(8)(12)= 320π feet^2
I hope this helps
