The graph is steeper ( as the slope 1/2 > 1/4) and has a lower y-intercept ( as -2 is less than -1)
A1 There are two ends so their combined surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side. The entire formula for the surface area of a cylinder is 2 π r2 + 2 π r h. so add the number of the height and radius plug in and you will get the answer for that.
x =65/2 = 32.5
y = 180 - 2(65)
y = 180 - 130
y = 50
hope it helps
The answer would be 6(y+x).
