If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
What is the circumference if a circle has a radius of 226.08 dm and a diameter of 36dmo f?
Such a circle is impossible. The radius of a circle is half its diameter.
What is the relationship between the Radius to the circumference?
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
What is the radius of a circle circumference is 38?
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
How do you find the diameter and radius of a circle with a circumference of 2 inches?
Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches
What is the circumference of a 6 diameter circle halfway?
A circle with a diameter of 6 has a circumference of 18.85. Half of that is 9.425
What is the circumference of circle with radius of 3 inches and diameter of 10 in ches?
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
What is the circumference of a circle if the diameter is 6 and a half inches.?
The circumference of any circle is (pi) multiplied by its diameter.To me, the most convenient number to use for (pi) is 22/7 .
What is the radius of a circumference circle?
radius is half the diameter of a circle.
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
If a circles radius is 20 inches what is the circumference?

Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
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).
How to find the radius of a circle with the circumference?
Divide circumference by pi, that gives diameter. Radius is half of diameter
What is the circumference if a circle has a radius of 226.08dm and a diameter of 36dm?
Such a circle is impossible. The radius of a circle is half its diameter.
What is a diameter and how is it used?
a diameter is the length of a circle at its widest point. It's used in finding the circumference of a circle (the area around) by multiplying pi (3.1415926535897........ it goes on, as its infinite) by the diameter. a radius is half the diameter, or the center of the circle to any point on its circumference. If your still confused, the average diameter of an orange is about 4 inches, give or take.
