Answer:
They have the same slope
Step-by-step explanation:
Given
Coaster 1:


Coaster 2:


First, we calculate the slope (m) of both coasters


For coaster 1:



For coaster 1:



<em></em>
<em></em>
<em>By comparison, they have the same slope</em>
-circumference is equal to pi×diameter, area is equal to pi×radius^2
-28.26÷3.14=9, 9÷2=4.5, 4.5×4.5=20.25, and 20.25×3.14=63.585
-rounded to the nearest hundredth, the answer is 63.59
