Is a Ferris wheel sin or cos?
One of the most common applications of trigonometric functions is, Ferris wheel, since the up and down motion of a rider follows the shape of sine or cosine graph.
How do you find the radius from the diameter?
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.
What is the radius of a 20cm circle?
You see the radius is 1/2 the diameter and 1/6 the size of circumference….Look at the table.
| Radius | Diameter | Circumference |
|---|---|---|
| 10cm | 20cm | 62.4cm |
| 20cm | 40cm | 124.8cm |

How do you calculate circumference of a pipe?
How to Calculate the Circumference of a Pipe
- Measure the diameter of the pipe. For example, assume the pipe has a diameter of four feet.
- Determine how accurate your measurement needs to be. If you need a general estimate, you can use 3.14 as pi.
- Multiply the diameter by pi. In the example, four feet times 3.14 equals 12.46 feet.
What is the circumference of a 8 inch pipe?
Pipe Sizes Info
| Standard Nipples and Pipe Sizing | ||
|---|---|---|
| Pipe Size | Outside Diameter (O.D.) | Circumference |
| 5″ | 5.563″ | 17.476″ |
| 6″ | 6.625″ | 20.812″ |
| 8″ | 8.625″ | 27.095″ |
How do you find the degree of a pipe?
Generally wrapping a flat tape around the item and coming up with a measurement is a good first step. Once you have this done, use the number that you have, convert it to inches and a decimal and then divide this number by 360 to determine the running distance for each degree increment from the reference point.
How do you calculate the angle of a pipe bend?
Fortunately, for those needing to measure the radius of a pipe that has already been bent, the process is much simpler. Multiply the circumference measurement from Step 1 above by 2. This is for a 180-degree pipe bend as shown in the graphic. For a 90-degree pipe turn, multiply by four at this point.
