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>
Shorter. Because of the way the arches work. the pink dot is the center.
Do 81/3=27/3=9/3=3, So you see the answer is 3^<span>4, I don't know if that's the official way to solve it but it works.</span>
If 3 people are going to the store each day
the probablity is 100%
