You can put this solution on YOUR website! Did you try searching for the surface area of a cylinder with a circular base online?
Let A = surface area of cylinder with circular base
Let r = 7
Why 7? If the diameter is 14, the radius is 1/2 of the diameter length and so 14 times 1/2 = 7.
Let h = 14
Let pi = 3.14
The formula to use is A = 2pi(r^2) + 2pirh.
Just plug and chug.
Here is the set up and you can do the math to find A.
A = 2(3.14)(7)^2 + 2(3.14)(7)(14)
Can you finish?
Just use your calculator to find A.
