If a circle has a circumference of 26 the diameter is: 8.276
26
The circumference of a circle is obtained by multiplying the diameter time pi (3.1416...). 26 inches times pi = 81.68 inches.
Diameter and height
area = π x (diameter ÷ 2)2 = π x (26 ÷ 2)2 = 169π ~= 531 sq ft.
This completely depends on the wheel. The most common number of spokes per wheel is 36. Some better wheels have 32. Higher performance wheels have even less.
Spokes are the thin metal rods that run from the hub(the center of the wheel) to the rim( the hoop where the tire sits). Inches usually refers to the approximate size of the wheel, 20" for BMX, 26" for MTB, and 28" for road bikes.
It is: 26/2 = 13 inches

Depends on what you mean and what the different bikes are like.If you really mean hub:The hub is the center part of the wheel, that holds the wheel axle and the spokes, and in some cases the brake rotor.Most 26" MTBs these days use dic brakes, while BMXes mostly use rim brakes. And to be able to fit a brake rotor to the finished wheel, you need to start with a disc brake hub, which a BMX hub is unlikely to be.But using a rim brake BMX hub to build into a rim brake MTB wheel - no problemAlso, most MTBs use 32 spokes, while for BMX, 36 spoke is more common. You need to match hub spoke count to rim spoke count to avoid complicated builds.If you mean wheel:BMX regular size is 20" against MTB regular size 26". You'll get all sorts of troubles by dropping 6" from the wheel diameter. The bike will handle differently, and the pedals will drop a lot closer to the ground.
A wheel with a 26 inch diameter has a circumference of 81.68 inches. At 145 rpm a point on the circumference travels at 145*81.86 inches per min = 11843.8 inches per minute.
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches

Circumference is diameter times Pi, so diameter is circumference divided by Pi. Now you do the math. That would make it 16.
If a circle has a circumference of 26 the diameter is: 8.276
half of the diameter.
By definition those are 26"(in diameter) wheels, but the exact size would depend on the tires that are on.
