How much does a radius measure?
A radius measures the distance from the center of a circle to any point on its circumference. It is half the length of the diameter, which is the distance across the circle passing through the center. The radius can vary in size depending on the specific circle being measured.
How would you find the radius of a circle with a circle with a circumference of 68cm?
First, divide the circumference by Pi (about 3.1416): 68 / 3.1416 = 21.65 cm. This is the diameter. Now, divide the diameter by two to get the radius: 21.65 / 2 = 10.825 cm.The radius is: 10.825 cmNote: The result will vary slightly depending on the value you use for Pi
What does pi the formula in math stands for?
In certain formulas, including most that involve circles, you will see 'pi'. This pi always has the same value, approximately 3.14159... However, this number is irrational, which means it never terminates (ends) or repeats. But what exactly is pi? Pi is the ratio between any circle's circumference and its diameter. This ratio is always the same, no matter how big or small the circle is, but the degree of precision might vary depending on how big the circle is. Why is Pi useful? Pi allows us to calculate the diameter or area of any circle, but also has many other uses. In order to use these formulas, though, we need to define the terms we are using. Circumference - the distance around the circle Diameter - the length of a straight line segment that passes through the center of the circle Radius - the distance from the center of the circle to the circle itself To calculate the circumference, multiply the diameter by pi (3.14...) To calculate the area, square the radius, then multiply this by pi (3.14...) In symbols: Circumference = diameter x pi Area = (radius)2 x pi Hope this helped.
What is the circumference of an artery?
The circumference of an artery can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the artery. The radius can vary significantly based on the type and location of the artery within the body. For example, the aorta, the largest artery, has a radius of about 1.5 cm, resulting in a circumference of approximately 9.4 cm. However, smaller arteries will have much smaller circumferences.
What name is given to part of the circumfrance of a circle?
The part of the circumference of a circle is called an "arc." An arc is defined as a segment of the circle's boundary, formed between two points on the circle. The length of an arc can vary depending on the angle subtended at the center of the circle.
In a circle the circumference and diameter vary directly Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second ci?
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?

Can the diameter be bigger than the circumference?
You cannot really compare those two different kinds of values - it's quite nonsense to compare area versus circumference. You could compare numbers but they'll vary depending on your choice of units. Anyway, it's perfectly possible to have shape of area, say, 1 m2 and circumference measured in kilometers - if the shapes perimeter is ragged.
What makes one circle different from another?
The defining characteristics of a circle are its radius, diameter, circumference, and area. Each circle is unique based on these measurements, which can vary in size and shape in comparison to another circle. These measurements determine the position and scale of the circle in space.
What is the difference between the area and the circumference of number eight?
Do you mean the geometrical shape that is the character "8" ? If so then drawn in its simplest form as two tangential circles not necessarily of the same radii, so obviously: - the circumference of each circle will vary with its ownradius, and - the area of each circle will vary as the square of its own radius; and the combined circumference or area will be the sum of the two individual ones respectively. I can't say I've ever had to calculate areas and perimetersof characters but I suppose you might if you are in sign-making or neon-lamp manufacturing!

How do you find the radius given the chord length?
If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
How many million kilometers is earth to the sun?
The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius.
What is the circumference of an atomic's bomb explosion?
The circumference of an atomic bomb explosion can vary depending on the size and yield of the bomb. In general, the blast radius of a typical atomic bomb explosion can extend several miles from the epicenter.
What is the volume of a soccer ball?
Because the circumference can vary from 68 to 70 centimeters, the volume is approximately 5310 to 5792 cubic centimeters(324 to 353.5 cubic inches).Circumference 68 cm = Radius 34/pi = Area 5309.77 cm3Circumference 70 cm = Radius 35/pi = Area 5792.19 cm3
What is one possible cross section of a sphere?
One possible cross section of a sphere is a circle. When a plane intersects the sphere, the shape of the intersection can vary depending on the position of the plane. If the plane cuts through the center of the sphere, the resulting cross section will be a circle with the same radius as the sphere. If the plane intersects the sphere at other points, the cross section will still be a circle, but its radius will be smaller.
