Yes, I can help you.
The formula to find the surface area of a cylinder is:
SA = 2πr² + 2πrh
where r is the radius of the cylinder and h is its height.
We are given the diameter of the cylinder, which is 14 cm. To find the radius, we need to divide the diameter by 2:
r = d/2 = 14/2 = 7 cm
Now we can substitute the values of r and h into the formula:
SA = 2π(7)² + 2π(7)(18)
SA = 2π(49) + 2π(126)
SA = 98π + 252π
SA = 350π
So the surface area of the cylinder in terms of pi is 350π square centimeters.
