<span>They are both functions of the cube of the radius or even the cube of the diameter for that matter, since one is a linear function of the other.
V=(4/3) pi r^3
If you do volumes of both, the (4/3) and the pi cancel
Do ratios of r^3 Thats just an example</span>
Answer:
v=52.5
Step-by-step explanation:
the angle is right so both of the sides should equal 90 degrees
90-(minus)37.5 is 52.5

Answer:
y = x - 9
Step-by-step explanation:
Keep in mind that the lines t and u are perpendicular, which implies that their slopes are negative reciprocals of one another. The negative reciprocal of the slope -1 of line t is +1.
Thus we need to find the equation of line u, knowing that the slope of this line is +1. Starting with the slope-intercept form y = mx + b, we find b:
y = mx + b becomes
-8 = (+1)(-1) + b, or -8 =-1 + b. Then b = -9, and the desired equation is
y = x - 9
