Question

Find the surface area of a cylinder with a diameter of 34 and height of 10. Use 3.14 for π. Round your answer to the nearest tenth.

Answer 1

The formula for the surface area of a cylinder is:
$A=2\pi rh+2\pi r^{2}$

As you probably know, the diameter is 2 times the radius, so by dividing the diameter, 34, by 2, we get 17 to be the radius.

Now, just plug the numbers in:
$A=2\pi rh+2\pi r^{2}\\ A=2(3.14)(17)(10)+2(3.14)(17)^{2}\\ A=1067.6+1814.92\\ A=2882.5$
