Wheel movement of one revelution equals one circumference ( in feet ).
Calculate that from the given info of radius ( in inches ).
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
The outer radius is 20/2 = 10 inches
radius=13 area=40.82 circumfrence=8.28025477707
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
pi radius squared. (radius squared, then multiply by pi.)
Find how far one revolution goes - this is the circumference of the wheel; from this the radius can be calculated: 1000 revolutions = 628m 1 revolution = 0.628m =62.8cm Circumference = 2{pi}radius (pi ~= 3.14) radius = circumference / 2{pi} ~= 62.8cm / (2 x 3.14) = 62.8cm / 6.28 = 10cm
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
The outer radius is 20/2 = 10 inches
3328.4 inches
5000 revolutions in 11000m = 1 revolution every 2.2m Circumference is 2.2m Circumference is diameter times pi 2.2m dividied by pi divided by 2 (to go from diameter to radius) = 35.014cm
My answer is 12
Radius of the wheel: 24/2 = 12 inches
radius=13 area=40.82 circumfrence=8.28025477707
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
12 inches
The wheel's circumference is: 219.9 centimeters.
The radius of a circle is defined as the distance from the centre-point to the circumference.
