We had this question just the other day as well. 28-21, you do the math.
28 - 21 = 7Which 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=7The 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?
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches
radius=13 area=40.82 circumfrence=8.28025477707
Circumference C=Pi*d = Pi*27 ~= 84.823 inches You will travel about 84.823 inches per revolution.
The inches in a diameter = 2 X inches in the radius. Or, inches in a diameter = inches in circumference / pi
22 inches because pi=3.14 and 28-21=7 and 7x3.14=22
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

12 inches
My answer is 12
Area of bicycle wheel: pi*13 squared = 169*pi or about 531 square inches
Radius of the wheel: 24/2 = 12 inches
14 - 10.5 = 3.5. The difference is 3.5 inches.
Frisbees come in different sizes. The diameter can be 8 inches, 10 inches, 12 inches, or another diameter.
Diameter is 10 inches.
81.7 inches
Area of circle with 18 inch diameter = pi*(18/2)2 = 81*pi sq inches Area of circle with 9.6 inch diameter = pi*(9.6/2)2 = 23.04*pi sq inches Difference = (81 - 23.04)*pi = 182.09 sq inches.
