Answer:
-26
Step-by-step explanation:
Dropping here means subtracting. That means that we calculate:
-10 - 16 = -26
Volume of a cylinder is h x r^2 x pi
You have the volume and radius of each one, so taking 188.4=(2)^2 x 3.14 x h1, you can solve this equation for the height h1. Likewise, for the other graduated cylinder you take 314=2^2 x 3.14 x h2, and then solve for h2.
To get the difference in heights, just take h2-h1 after solving the equations for h2 and h1
3.5 because 42 divided by 12 is 3.5
Tan30=x/18yd
x=0.57734 x 18
x=10.4yd
Answer:
3619.11 cubic inches
Step-by-step explanation:
volume of a cylinder is 
diameter is 16 in, so radius (r) is 8 in
plug in values:
cubic inches
