Mrac [35]
For this case we can model the problem as a rectangle triangle.
 We have:
 Length of the sides of the triangle.
 We want to find:
 Length of the hypotenuse.
 Using the Pythagorean theorem we have:
 d ^ 2 = 2 ^ 2 + 2 ^ 2

 d =  \sqrt{2 ^ 2 + 2 ^ 2} 

d =  \sqrt{4 + 4} 

d =  \sqrt{8} 

d =  2\sqrt{2} 

 Answer:
 
She is:
 
d = 2\sqrt{2}
 miles far from her starting point

The diameter of the base of the cone measures 8 units.
kati45 [8]

Answer:   32\pi cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

V_{cone}=\frac{1}{3}\pi r^2h

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

r=\frac{8units}{2}\\\\r=4units

Since you already know that height and  the radius, you can substitute them into the formula. Then, the volume of this cone is:

V_{cone}=\frac{1}{3}\pi (4units)^2(6units)

V_{cone}=32\pi \ units^3
