The radius would be 10 inches. Not sure about a radious, though.
If that is the diameter, divide by 2 to get the radius. Then use the formula: area = pi x radius2.
Diameter = 20 inch => radius = 10 inches = 10/12 feet. So area = pi*(10/12)^2 = 2.1817 sq feet approx.
Twice pi multiplied by the radius will get you the result. Pi, if you are going to round to the inch, call it 3.14. The radius will be half the diameter...20 inches. Find a calculator and multiply 2 X 3.14 X 20...you can do it. You can also multiply pi times the diameter and get the same result.
20; the diameter of a circle is twice its radius.
20 inches will be the 'diameter' so the 'radius' will be 10 inches.
20 inches measured where on the wheel? Radius? Diameter? Circumference? Width?
The radius will be half the diameter which is 20/2 = 10 inches
Of course not. You need 20 inch wheel to mount 20 inch tires.

Area = pi*r2 So r = 20 inch gives area = 1256.64 sq inches.
Bicycles have pretty standard tire sizes from 16, 18, 20, 24, 26, 29 inch. There may be some special sizes out there. 26 is pretty standard for adult bikes.
It'd be pretty hard to decide what's the average bike wheel is. For the MTB crowd it's 26", for the road crowd it's 28", then you've got all the BMXes and kids bikes which'll be something different. Twice its radius, and entirely dependent on which size it is. Bicycle wheels come in a wide variety of sizes, usually between 12"-28".
The standard wheel size is a 16 inch wheels. There are options available for larger wheels, such as a 17 inch, 20 inch, and 22 inch wheels.
17 inch or 20 inch
