To solve this problem, we simply use the equation of
volume for hollow cylinders:
V = π h (R^2 – r^2)
where V is volume, h is height = 10, R is outer radius =
8.4/2 = 4.2, r is inner radius = 6/2 = 3
V = π (10) (4.2^2 – 3^2)
<span>V = 86.4π = 271.43 mm^3</span>
Answer:
yes
Step-by-step explanation:
the variable cannot have a negative symbol, unless it has no number.
Answer:
15/2
Step-by-step explanation:
My interpretation of your math expression is "2 1/2 divided by 1/3."
I prefer to write this as:
5 1
----- ÷ -----
2 3
which is equivalent to:
5 3
----- * ----- = 15/2
2 1
The answer is D. -2x+5.
If we simplify the left side of the equation first given, we come to the expression -2x-10.
If we solve for D., we get the same results. Thus, because an equation with all the same variable terms and constants have infinite solutions, the answer is D.
Hope this helps!
