## What is the volume of a ring?

Ring volume formula: V=π2∗(R+r)∗(R−r)2.

## How do you find the volume of a circle calculator?

Circular Cylinder Volume

1. Volume = πr2h.
2. Top Surface Area = πr2
3. Bottom Surface Area = πr2
4. Total Surface Area. = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

## How do you calculate net volume?

Net volume is a technical indicator calculated by subtracting a security’s uptick volume by its downtick volume over a specified period of time. Unlike standard volume, the indicator differentiates whether the market sentiment is leaning bullish or bearish.

## What is a bored well?

Dug/Bored wells are holes in the ground dug by shovel or backhoe. They are lined (cased) with stones, brick, tile, or other material to prevent collapse. Dug wells have a large diameter, are shallow (approximately 10 to 30 feet deep) and are not cased continuously.
