Answer: Point R will be at the number 8 on the number line.
From -8 to 12, there are 20 numbers. If we want to get a ratio of 4:1, we need to have 5 equal sections.
20 / 5 = 4
Since the ratio is 4:1 to R, we need to move 4 x 4 = 16 spaces from -8.
-8 + 16 = 8
Look for the equation that gives you a value of 8.
The answer is -45 and 36 because -45+36=-9
59.346
V = pi * r^2 * h
V = 3.14 * 3^2 * 2.1
V = 3.14 * 9 *2.1
V = 3.14 * 18.9
V = 59.346
