![\dfrac{2}{3}\pi r^3 $ cubic units](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3%20%24%20cubic%20units)
Step-by-step explanation:
Given a cone of base radius, r and perpendicular height, h
![\text{Volume of the cone }=\frac{1}{3}\pi r^2 h](https://tex.z-dn.net/?f=%5Ctext%7BVolume%20of%20the%20cone%20%7D%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20h)
Since the height of a cone is twice the radius of its base.
![\text{Volume of the cone }=\dfrac{1}{3}\pi r^2 (2r)\\=\dfrac{2}{3}\pi r^3 $ cubic units](https://tex.z-dn.net/?f=%5Ctext%7BVolume%20of%20the%20cone%20%7D%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20%282r%29%5C%5C%3D%5Cdfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3%20%24%20cubic%20units)
The expression that represents the volume of the cone, in cubic units is

Answer:
The height = 8 miles.
Step-by-step explanation:
Area of a trapezoid = h(a + b)/2 where h=the height and a and b are the 2 bases.
So we have:
21.2 = h(4 + 1.3)/2
5.3 h / 2 = 21.2
5.3h = 42.4
h = 42.4 / 5.3
h = 8.
Answer:
The answer is -2
Step-by-step explanation:
slope = y2-y1/x2-x1
= -6-6/3-(-3)
= -12/3+3
= -12/6
= -2
