a straight trail with a uniform inclination of 11 degrees from a lodge at an elevation of 700 feet to a mountain lake at an elev
kozerog [31]

Answer:

r = 38584.155\,ft

Step-by-step explanation:

The length of the trail is obtained by the definition of sine, where height is the opposite leg and length is the hypotenuse:

\tan 11^{\textdegree} = \frac{8200\,ft-700\,ft}{r}

The length of the trail is:

r = 38584.155\,ft

I really need help on geometry
balu736 [363]
For example, exc. 15.

x + y = 10 and 6/x = 9/y; You need y!

=> x = 10 -y and 9x = 6y => 9(10-y) = 6y => 90 - 9y = 6y => 15y = 90 => y = 6.

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?
grigory [225]

Answer:

\frac{4}{3} \pi r^3.

Step-by-step explanation:

Let's say that the radius is r. The base diameter is two times the radius, or 2r.

Since the height is two times the diameter, the height is 2 * 2r = 4r.

The volume of a cone is 1/3 * h * pi * r^2. So, the volume of the cone is 1/3 * 4r * pi * r^2 = 1/3 * pi * 4r^3 = 4/3 * pi * r^3.

So, the volume of the cone is \frac{4}{3} \pi r^3.

Hope this helps!
