I believe the answer is the first one because it contains a negative fraction and in the chart some of the numbers are negative
There is a Math website that has a lot of Calculus story problems. He shows you how to solve problems.

Based on the given parameters about old cone, the height of the new cone is 12 inches
<h3>Equivalent ratio</h3>
Old cone:
- Radius, r = 2 inches
- Height, h = 6 inches
New cone:
- Radius, r = 4 inches
- Height, h = h
equate ratio of radius to height in old and new cone
2 : 6 = 4 : h
2/6 = 4/h
cross product
2 × h = 6 × 4
2h = 24
h = 24/2
h = 12 inches

Answer:
V=97.08
Step-by-step explanation:
The formula for the volume of a cone is V= 1/3 pi (r)^2 (h)
To find the radius divide the diameter by 2. 6/2=3
Plugin: V=1/3 pi(3)^2(10.3)=97.08
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.
Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.
So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)
