In the linear equation y = mx + b, y-intercept represents the value of y. It is the point where the line crosses the y-axis(vertical axis)
Finding the y-intercept is done by looking at which point in the graph crosses the y-axis. This point will always have an x-coordinate of zero(0).
It could be 8 since 8x18= 144 and 144 divided by 2 is 72
I don’t think it is, sorry I’m not 100% sure, good luck though
V = 1/3 * (pi) * r^2 * h
(pi) = 3.14
r = 6
h = 3
V = 1/3 * (3.14) * 6^2 * 3
V = 1/3 * 3.14 * 36 * 3
V = 1/3(339.12)
V = 339.12 / 3
V = 113.04 cubic inches <==
