The required values are ~
Refer to attachment for solution ~
24 divide by two is 12
so x is 24
It's 8 because the number in front of the variable is the slope, while the past 30 is the y intercept
Change each into a mixed number and simplify the mixed number
To find surface area of 3D objects, you have to know the area formulas for basic shapes. For example, the area of a circle is

and the area of a rectangle is length times width. To find surface area of a cylinder, you will need to know both of those formulas, since the 3D shape involves both circles and rectangles.
