With one rotation, the wheel advances one entire circumference.The circumference is radius times (2 x pi).To convert from centimeters to meters, divide by 100.Finally, just divide the total number of meters by the circumference (in meters), to get the number of turns.
20 inches measured where on the wheel? Radius? Diameter? Circumference? Width?
The spoke is the radius. Therefore 27/2pi is 4.297, the radius is rounded to 4.3 inches
The number of revolutions will be equal to the distance of the trip divided by the circumference of the wheel. We're already given the trip distance, and the circumference can be worked out from the radius we're given. Recall: the circumference of a circle is equal to pi multiplied by twice it's radius; or more formally:c = 2πrIn this case, r is equal to 28cm, so we can say:c = 2π28cm≈ 2 × 3.14159265 × 28cm≈ 175.929cmNow we can take the distance of the trip, 3km, and divide it by the circumference of the wheel, 175.929 centimeters. That will give us the number of revolutions for the wheel:R ≈ 3km / 175.929cmWe will of course have to convert the units first. There are one hundred thousand centimeters in a kilometer, so we can say:R ≈ 300000cm / 175.929cm∴ R ≈ 1705.232That gives us the number of revolutions that would be required, but the question asks how many complete revolutions are needed. This means the last 0.232 revolutions would not be part of our final answer. Instead we can say:R = 1705So the wheel must do one thousand, seven hundred and five complete revolutions for a three kilometer journey.
When the radius of a car wheel is 49 cm what is circumference of the wheel? The circumference is 307.8760800517997 centimeters
radius=13 area=40.82 circumfrence=8.28025477707
A 128 inch circumference would imply a radius of 20.4 inches - a regular bicycle wheel, for example.
You need to know the circumference or diameter or radius or size of the wheel
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
Wheel movement of one revelution equals one circumference ( in feet ). Calculate that from the given info of radius ( in inches ).
To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * Ο * 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 * Ο * radius, we can solve for the radius as 0.0044 km / (2 * Ο) β 0.0007 km, or 0.7 meters.
Radius of the wheel: 24/2 = 12 inches
A radius is not a specific unit of measurement - the radius of a circle is the measurement from the centre of the circle to any line on the circle's circumference. The word "radius" is derived from the Latin word for "ray" but was also used to refer to the spoke of a chariot wheel.
circumference = 2*pi*radius or diameter*pi
Circumference = 2*pi*radius or diameter*pi
Multiply the radius by 2 x pi.
