Answer:
Step-by-step explanation:

SA = 2 pi r * x + 2* pi r^2
r = 6
SA = 2 pi * 6 * x + 2 * pi * 6^2
SA = 12 pi * x + 72 pi
Volume = pi r^2 * x
Volume = pi 36 x
Now volume and surface area are made to be equal so
Volume = Surface area
36 pi x = 12 pi x + 72 pi Divide through by pi
36x = 12x + 72 Subtract 12x from both sides
24x = 72 Divide by 24
x = 72/24
x = 3
15 is done exactly the same way. You can try it yourself. Only the numbers are different. Use 10 for the radius. You should get x = 2.5
A triangle must have three closed sides, which means all of the lines are touching
