The equation used to calculate circumference is C = Pi * R^2, where R is the radius and C is the circumference. If one knows the circumference and seeks the radius, then they must divide by pi. Next, they must take the square root. When the circumference is 72, the radius must be approximately 4.8.
Wheel movement of one revelution equals one circumference ( in feet ). Calculate that from the given info of radius ( in inches ).
What?!! Radius cannot be measured in Newtons!
The formula for finding the circumference is C = Pi x D, where Pi = 3.1416 and D is the diameter. The Radius is one-half of the diameter., So, multiply the radius by 2 and then multiply by Pi.
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
The radius is half of the diameter. The radius of a circle is the distance from the centre to the circumference. The diameter of a circle is the length of a straight line from one point on the circumference to another, passing through the centre of the circle.
Circumference is pi * diameter, or pi * 2 * radius, so if you are given circumference, then radius = circumference / 2 / pi. Pi is approximately 3.1416 Radius is from the center to the edge. Diameter is twice that (from one edge, through the center to the other edge). Radius = Diameter / 2, so if you're given Diameter, then just divide by 2.
formula for circumference:P=2Ï€rP=2*3.14*4.6P=28.888 in= 28.89 in
circumference would be halved, area would be one fourth of original , andvolume would be one eighth of original.
Radius is the distance from the center point to the edge of the circle. Diameter is the distance straight through the center point and across the circle. Circumference is the distance one full turn around the circle. Radius = 1/2 of the diameter Radius = (circumference) divided by (2 pi) Diameter = 2 times the radius Diameter = (circumference) divided by (pi) Circumference = (pi) times the diameter Circumference = (2 pi) times the radius
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
it depends on what the radius is if they give you one
radius = circumference divided by 2 x pi so 10.99/6.28 = 175 centimetres
radius is exactly one-half of diameter. It is distance from center of circle to circumference. radius = 24.5/2 = 12.25
Divide the circumference by (2 x pi). Pi is approximately 3.14.
The circumference is (2 pi) times (the radius), and the area is (pi) times (the radius squared).The same statements are true for any circle, not only this one, so this is actuallyquite a powerful answer.
A chord touches two points on the circumference of a circle whereas a radius touches only one point from its center.
The radius is one -half of the diameter. It is the distance from the circle center to any point on the circumference.
The Radius is one-half of the diameter. The formula is R = D/2 The Circumference is the distance around a circle. The formula is C = Pi x D (Pi = 3.1416 and D is the diameter)
Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter diameter x pi = circumference (distance around) 2 pi radius is the circumference of a circle
98pi ie 307.9m to one significant figure
The circumference is 2 x pi x radius which makes 75.4 inches
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.
