360 / 30 = 12 , so 12 spokes in that wheel.
18. Picture it this way. If a wagon wheel had 2 spaces, it is easy to see that it would have two spokes, say, top and bottom. Adding another spoke would block off another space. From this idea, you can see that the number of spaces must equal the number of spokes.
Wheel movement of one revelution equals one circumference ( in feet ). Calculate that from the given info of radius ( in inches ).

360 / 15 = 24 spokes
A wheel with 10 spokes will have 10 spaces between the spokes.
A wheel with 64 spokes will have 64 spaces between the spokes.
The tire is only the rubbery part on the outside, and it hasn't got any spokes. The wheel (which also includes hub and rim) has spokes, usually 36 of them but other numbers are possible.
A wheel with 12 spaces will have 12 spokes.
360 / 30 = 12 , so 12 spokes in that wheel.
That would differ from one bike to another. A really small bike with maybe 12" wheels will have fewer spokes than a bike with 20" wheels. Say between 24 and 36.
There would be 20 spokes with 20 spaces. Picture each space as if it was a flag and each spoke as a flagpole.
It depends if you have a 3 piece crank, spokes, brakes.

Two wheels on a Penny Farthing: the front one is larger than the back one in proportions similar to the former currency items penny and farthing, which was only worth a quarter of a penny and was much smaller.
Wheels can have as few as a dozen or so spokes to well over 100 depending on the intended use, but traditionally most bike wheels on single rider bikes have had 28, 32 or 36 spokes and wheels on tandems have 40 or 48 spokes. Wheels with fewer spokes tend to have aerodynamic advantages for two reasons: firstly, the drag from the spokes themselves is reduced. Secondly, the reduced number of spokes means larger sections of rim are unsupported, necessitating stronger, deeper-section rims. Such rims tend to be aerodynamic, although there is often a weight penalty. More spokes usually means more strength and durability. However, equal and appropriate spoke tension is the key factor to strong bicycle wheels that remain true (circular and wobble-free).
