The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet

The diameter of a wheel is 6cm how many complete revolutions will the wheel make if it rolls a distance of 108pi cm?
Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
How many revolutions of a 12-inch wheel make 1 mile?
A 12-inch wheel has a diameter of 12 inches, which is 1 foot. The circumference of the wheel is π (pi) times the diameter, or π feet. A mile is 5,280 feet, so the 12-inch wheel must turn 5280/π or about 1,680.676 times.
The wheels circumference is how many times as big as its diameter?
A wheel is in the shape of a circle. The formula for the circumference of a circle is 2πr where r is the radius. But, the diameter of a circle is twice the radius so this equation can be written, Circumference = πd where d is the diameter. The Circumference is therefore π times as big as the diameter, π = 3.142 or 22/7 approx.
If the diameter of a wheel on Joshua's bike is 20 inches then what is the radius of the wheel?
The radius will be half the diameter which is 20/2 = 10 inches
What is the radius of a wheel with a diameter of 27.6cm?
Radius of wheel: 27.6/2 = 13.8cm
How do you find the distance traveled on a bike if you know the wheels diameter?
wheel diameter times pi times number of rotations
Why do you have to know the circumference of your bicycles wheel in order to set a cyclometer?
A larger diameter wheel rotates a fewer number of times to cover the same distance as a smaller wheel.
How many times will the wheel of a car rotate in a journey of 88km if the diameter of the wheel is 56cm?
50,020 times
How do you find diameter using rotations and distance?
Rotations and distance tells you about the circumference and this tells you about the diameter. How about a specific problem?
What is the diameter of the spokes wheel if its 26 cm long?
Assuming this question does not want to account for the axel of the wheel, or the rim around the wheel, we know that the spoke is equal to the radius of the wheel. And we know that the radius is equal to 1/2 times the diameter. So, 2(r) = d 2(26) = 52. So, the diameter is 52 cm long.
A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk returned to the same position the team then measured the distance the wheel?
They measured the distance the wheel traveled on the ground which would be the same as the circumference of the wheel. If they then measured the diameter of the wheel and divided the circumference by the diameter they would have a value for pi.
What is the linear distance traveled in one revolution of a 36 in diameter wheel?
36 pi
What is the linear distance traveled in one revolution of a 20 meter in diameter wheel?
Linear distance of one revolution = 3.14 x diameter = 3.14 x 20 = 62.8 meters
The diameter of the front wheel of a small bike is 20 inches In one full turn of the wheel the bike travels about?
Circumference is diameter times Pi, you do the math.
The diameter of a wheel is 6cm how many complete revolutions will the wheel make if it rolls a distance of 108pi cm?
Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
If the distance of a bicycle wheel is 21.98ft what is the diameter?
If its circumference is 21.98 feet then its diameter is 21.98/pi = 7 feet rounded up.
How does the mechanical advantage of a wheel and axle change as the size of a wheel increases?
The velocity factor of a wheel depends on its diameter. If we take the velocity factor as a measure of how far the vehicle moves in one revolution of the wheel, then it is equal to the circumference of the wheel, which is pi times the diameter.
