Volume of a cylinder: pi*r^2*h
volume of a right cone: (1/3)*pi*r^2*h
the volume of the cylinder is triple the volume of the cone
it's 18 inch^3
Answer is B 9
X/3=15/5
45/5
x=9
So answer B
-3(-4x + 2y = 12) 2(-13x + 3y = 46)
12x -6y = -36 -26x + 6y = 92
12x - 6y = -36
-26x + 6y = 92
-14x 0 = 56
-14x/-14 = 56/-14.
X = -4.
-4x + 2y = 12
-4(-4) + 2y = 12
16 + 2y = 12
-16. -16
2y/ 2 = -4/2
Y = -2
-4x + 2y = 12
-4(-4) + 2(-2) = 12
16 -4 = 12
12 =12
(-4,-2)
