The radius is 28 cm so the circumfecrence is 2*Ï€*28 cm = 56Ï€ cm
which is the distance travelled by 1 revolution.
So the distance travelled in 300 revolutions = 300*56Ï€ cm = 16800Ï€ cm = 52778.76 cm
= 527.8 metres approx

How do you find radius from revolution and distance?
Distance is number of revolutions times circumference. So divide the distance by the revolutions to get the circumference. Then divide the circumference by pi to get the diameter, and divide that by 2 to get the radius.
How do you solve for revolutions per second give centripetal force and radius?
One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.
How far will a wheel of radius 5 cm travel in two revolutions?
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.
What is the displacement of a person when he covers 0.5 the distance in a circular path of radius 5 meter?
If he covers 1/2 the length of the circular path, then the beginning and end of histrip are at opposite ends of a diameter of the circle.Diameter = 2 x radius = 2 x 5 = 10 meters.
The distance from Arcata to Crescent City is 86 miles A car was driven this distance using tires with a radius of 16 inches Approximately how many revolutions of each tire occurred on the trip?
Useful information: 86 miles tire radius of 16 inches In order to find how many revolutions the tire undertakes you must divide the amount traveld by the circumference of the tire (The length of tire tread). To find the circumference you multiply the diameter by Pi (3.14) The diameter is twice the radius or 32 inches 32 in. x 3.14 = 100.48 in. 86 miles equals 5,448,960 inches 5448960 in. /100.48 in. = 54229.3 revolutions
What is 4.5 RPM's converted into mph?
That depends on the radius of the wheel making the revolutions.
How many revolutions will a wheel make in travelling at 2 kilometers if its diameter is 700 millimeters?
If the diameter is 700 mm then the radius is 700/2 = 350mm The circumference of the circle is 2πr = 2π.350 = 2199.115 mm 1 kilometre = 1000 metres = 1000000 mm : 2km = 2000000mm Number of revolutions = distance travelled ÷ circumference of wheel. 2000000 ÷ 2199.115 = 909. 46 revolutions
If wheel of bicycle makes 1000 revolutions in travelling 628m what is its radius?
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
What is the distance from a circle to it's center?
It is called the radius. The full distance is called the diameter.
How many revolutions will it take if a wheel is rolled 30 times and has a radius if 3 inches?
30. The radius is not relevant. Each roll is one revolution.
How many complete revolutions will a bicycle wheel with a radius of 28cm make in a journey of 3 km?
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.
How many revolutions are required for a 10in radius to go 2000in?
2000/(10 * 2 * pi)
