If wheel of bicycle makes 1000 revolutions in travelling 628m what is its radius?
Swatibhandurge
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

How many turns must a bicycle wheel make of radius 0.5m make to travel a distance of 100m?
A wheel with a radius of 0.5m has a circumference of 2πr metres. In this example, 2πr = 2π x 0.5 = π metres. The wheel makes 100/π turns when travelling 100 metres, that is 31.831 turns.
A bicycle wheel makes 5000 revolutions in moving 11kmWhat is the radius of the wheel?
To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * π * radius. Since the wheel travels a distance of 11 km in 5000 revolutions, each revolution covers a distance of 11 km / 5000 = 0.0022 km. The circumference of the wheel is twice the distance covered in one revolution. Thus, we have Circumference = 2 * 0.0022 km = 0.0044 km. By setting up the equation 0.0044 km = 2 * π * radius, we can solve for the radius as 0.0044 km / (2 * π) ≈ 0.0007 km, or 0.7 meters.
Jims bike wheel has a radius of 10 inch explain how to determine how many feet the bicycle will travel if the wheel makes 1 revolution?
Wheel movement of one revelution equals one circumference ( in feet ). Calculate that from the given info of radius ( in inches ).
