6/ 2/3 that the answe ti that that should be the answer
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:
I think 9 and 12 are paraellograms. the others are not paraellograms. dunno if im right. but I tried my best
Step-by-step explanation:
Like
you said: 10 beats per minute, which is 20% percent of its normal value.
So:
10 per minute is 20% of the normal rate. You will divide each side by 0.2, which
will result in 50 per min
