What is the radius of a circle if the circumference is 72?

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.


What is the circumference of a circle with a radius of one and one third?

8.37758


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 ).


Circumference of universe within the radius of one newton?

What?!! Radius cannot be measured in Newtons!


How do you you find the circumference if you have the radius?

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.


What is circumference and diameter and radius?

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).


Why are radius and diameter different?

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.


How can you find the radius with the given measurement?

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.


Find the approximate value of the circumference of a circle with the given radius Use equals 3.14 Round your results to one more decimal than in the given radius 4.6 inches?

formula for circumference:P=2Ï€rP=2*3.14*4.6P=28.888 in= 28.89 in


What do you think would happen if you halved the radius of a circumference?

circumference would be halved, area would be one fourth of original , andvolume would be one eighth of original.


What is the relationship between radius diameter and circumferences of circles?

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


Is the radius one fourth of the circumference?

No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)


What is one half of the diameter equals the?

radius.


How do you find the approximate circumference of the inner circle?

it depends on what the radius is if they give you one


What is the radius of a circle with a circumference of ten point nine nine metersUse three point one four?

radius = circumference divided by 2 x pi so 10.99/6.28 = 175 centimetres


What is the radius of a circle with a diameter of 24.5?

radius is exactly one-half of diameter. It is distance from center of circle to circumference. radius = 24.5/2 = 12.25


What is the radius of a circle with a circumference of fourteen point one three meters?

Divide the circumference by (2 x pi). Pi is approximately 3.14.


What is the circumference and the area of a circle with a radius of 9 yards?

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.


How is a chord different from a radius?

A chord touches two points on the circumference of a circle whereas a radius touches only one point from its center.


How do you calculate the radius from the diameter of a circle?

The radius is one -half of the diameter. It is the distance from the circle center to any point on the circumference.


How do you find the radius and circumference of a circle?

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)


What is 2 pi radius?

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


What is the circumference of a circle with a radius of 49 meters?

98pi ie 307.9m to one significant figure


How far does a tire with a 12-inch radius travel in one revolution?

The circumference is 2 x pi x radius which makes 75.4 inches


How many times a wheel of radius 28 cm must rotate to cover 704 m?

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.
