The height of the cone is 4 cm (approx).
Step-by-step explanation:
Given,
The radius (r) of the cone = 4.96 cm
Volume (V) = 102 cm³
To find the height (h) of the cone.
Formula
The volume of a cone V = πr²h
Now,
According to the problem,
πr²h = 102
or, ××(4.96)²h= 102
or, h =
or, h = 3.95 = 4 (approx)
so,
Height = 4 cm (approx)
8n + 12 +(-9) -(-6n)
12 + -9 = 12-9 = 3
8n - (-6n) = 8n + 6n = 14n
The equation becomes 14n + 3

Answer:
80% because if she finished her project it would be 100%, but if we subtract 20% from 100, it would be 80% so she has 80% left to complete

The distance between the boat and the ocean's floor is 19m
<h3>
How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
