28 - 21 = 7
Which is a fairly silly answer as there are no 21" bike wheels. The spoke thing is quite misleading, as there are several things that aren't mentioned here that affect spoke length.
If stood side by side the 28" wheel will reach 7" higher than the 21" wheel.
7 inches difference . As 28-21=7
The diameter of one bicycle wheel is 28 inches and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel 21 inches. What is the difference in inches between the length of the spokes of the two wheels?
We had this question just the other day as well. 28-21, you do the math.
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
Circumference is equal to the diameter multiplied by pi, or 3,14. Multiply 65 x 3.14.
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches

The diameter of one bicycle wheel is 28 inches and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel 21 inches. What is the difference in inches between the length of the spokes of the two wheels?pi * diameter = circumference, if that's what you're looking for. But be aware that the numbers and sizes used to describe bicycle tires are often very inaccurate. So all you have to do is just subtract 28 from 21 and divide your answer by two!! 28-21=7 7/2=3.5
We had this question just the other day as well. 28-21, you do the math.
22 inches because pi=3.14 and 28-21=7 and 7x3.14=22
A female bicycle have bigger seat than the male bicycle. That's how you know the difference.
The difference between you and the bicycle you ride on is that you are a living thing that breathes while the bicycle is a machine classified as a non living thing.
a car is faster and much safer then a bicycle. your welcome
A bicycle is powered by human exertion and a motorbike by mechanical power.
A motorcycle has a motor and no pedals
This is the answer to the question, What is the difference between an orange?
Riddle: What is the difference between a bicycle that falls from a rooftop and one that is destroyed in an explosion?Answer: If a bicycle falls from a rooftop, then there it is. But if it is destroyed in an explosion, then where is it?
A moped has the ability to be manually pedaled (like a bicycle). A scooter does not.
The circumference of the wheel is Pi multiplied by the diameter (0.705). Divide 1000 meters (1km) by that answer - and you'll have your solution !
