I'm pretty sure the answer would be 2.
Sorry if it's wrong
Its y = -4/3x -6
so-4/3 is slope
Volume of the cone: 1/3 of area of the circle * the height
(1/3)π5²*5=(125/3)π
volume of the cylinder: area of the circle *the height: π5²*10=250π
add up: (125/3)π+(125/3)π+250π≈1047.2
D is the correct answer
X = 2
y = 3
You can simply set these two equal to each other and solve for x. Then plug in to find y.
