Answer:
V = 402.12385mm
Step-by-step explanation:
When the diameter is 8mm, the radius is 4mm.
V = (π(4^2))8
V = (16π)8
V = (50.2654)8
V = 402.12385
V ≈ 402, 402.1, 402.12, 402.124
Answer:
-1
Step-by-step explanation:
can be soled by substitution remember BEDMAS
can also be written like this
((-2)-2*(-0.5))^3

∘
Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around
170
∘
, but we can rule that out as a value for a ramp wedge angle.
Answer:

Step-by-step explanation:
17/20
Multiply by the conjugate 5/5.
(17 × 5)/(20 × 5)
85/100
Apply rule : a/100 = a%
85/100 = 85%
