an image shows a cylinder with a radius of 18 and a height of 15, what is the surface area in terms of pi
The formula for the surface area of a cylinder is given by:
SA = 2πrh + 2πr^2
where r is the radius and h is the height of the cylinder.
Substitute r = 18 and h = 15 into the formula:
SA = 2π(18)(15) + 2π(18)^2
SA = 2π(270) + 2π(324)
SA = 540π + 648π
SA = 1188π
Therefore, the surface area of the cylinder with a radius of 18 and a height of 15 is 1188π.
