What is the formula in finding the volume of a cone?
The formula for the volume of a cone is V=1/3hπr².
How do you find the radius in inches?
Locate the circle’s center, and measure the length from its center to a point on its edge to find the radius. For an example, suppose the measurement is 5 inches. Double the length to calculate the circle’s diameter. For this example, multiplying the length of 5 inches by 2 results in 10 inches.
What is the minimum radius for HO trains?
15 to 22 inches
Is 18 inch radius big enough for my ho passenger trains?
Eighteen inches is the recommended minimum, and is at the bottom end of the range of “tight” curves for HO scale. It’s a fact…that long engines and passenger cars or auto-racks look rather silly on really tight curves, even if they can actually get around them 100% of the time.
What is the radius of a 4 degree curve?
Degrees of Curve to Radius
| Degree of Curve | Radius, Scale Feet | Radius for HO (Inches) |
|---|---|---|
| 1 | 5729.651 | 789.389 |
| 2 | 2864.934 | 394.710 |
| 3 | 1910.078 | 263.156 |

Can ho trains run on OO track?
HO trains run on a 16.5mm gauge track. OO scale is generally only used for models of British prototype. It is 1:76th scale or 4mm to the foot. The trains still run on the same 16.5 mm gauge track as HO models.
Which is better N scale or HO scale?
An advantage of N scale is that it allows hobbyists to build layouts that take up less space than HO scale, or put longer track runs into the same amount of space, because the models are smaller (by nearly a half) than they are in HO scale (1∶87).
