20 points because this is evil! and due at 8am tomorrow, btw.

part a: what is the total surface area of the tower? round your answer to the nearest hundredth.

part b: another tower is constructed by placing the original tower on top of another cylinder with a height of 18 inches and a radius of 54 inches. what is the total surface area of the new tower? round your answer to the nearest hundredth.

i know the end result of the entire problem is 14,249.5in squared, but i can't figure out how to get to that answer. could anyone me?

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
