What is the circumference of a circle with a radius of 5 inches?
Q : What is the circumference of a circle with a radius of 5 inches ? Ans: The formula to calculate the circumference is 2 X Pie X radius. The value of radius is given as 5 inches. Substituting the value of r in the above formula then we get as the value of Pie is 22/7 = 2 X (22/7) X 5 = 220/7 = 31.41 sq. Inches. Also, Q: What is the circumference of a circle with a radius of 12inches?? A: The circumference is 75.366 inches, because the formula is 2 x Pie x r
How is the value of pi equals 3.142?
The circumference of a circle divided by the radius. (Works on any circle)
Can the cumference of a circle be found?
Yes. you need to know the diameter or radius of the circle and then the formula is:- Circumference = Pi*Diameter or Circumference = 2Pi*Radius. An approximate value for Pi is 3.14159.
How do you find a circumference of a circle that has a fraction as a radius?
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
What is the formula for the circumfrance of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter

What's is the circumference of the circle if the radius is 10 in?
The circumference of a circle is equal to 2 times pi times the radius of the circle. Therefore, if the radius of the circle is 10 inches, the circumference would be 2 times pi times 10 inches, or 20 pi inches. Pi is a mathematical constant with a value of approximately 3.14, so the circumference of the circle would be approximately 62.8 inches.
If the circumference of a circle is 31.40 inches what is the radius?
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
What is the definition of cercumference and radius of pi.?
Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
How do you find the radius of a circle when the circumference is given?
Divide the circumference by the value of Pi, then halve that result.
What is the radius of a circle that has a circumference with the same numerical value as its area?

How many square inches in a 4.25 inch circle?
A circle that is 4.25 inches implies that its circumference is 4.25 inches; that is, it is 4.25 inches around. The formula for the circumference of a circle is given as c = 2πr, where c is the circumference, pi is a constant (approximately 3.14), and r is the radius of the circle. Since the c-value is known we can use algebra to manipulate the formula in order to solve for r (the only missing piece of information). Doing so yields r = c/2π. Substituting the circumference of 4.25 inches into the formula reveals that the radius must be .68 inches (rounded to two decimal places). Now that the radius of the circle is known, the surface area can be calculated with the formula A = πr2. Substituting the determined value of the radius in for r produces a surface area of 1.45 inches2. The unit of square inches comes from the fact that we are not only multiplying the numerical value of the radius, but also its units. In this case, r2 = (0.68 inches)(0.68 inches) = 1.45 inches2.
What is the radius if the circumference is 12 inches?
The radius and circumference of a circle are related as C=2*pi*R (* stands for multiplication) where C is the circumference(=12 inches in the given case), R is the radius(to be found out) and 'pi' is a constant whose value is approximately 3.141592654. To find R the formula becomes R=C/(2*pi). Substituting 12 inches for C and the value of 'pi' we arrive at the following result: R or radius=12/(2*3.141592654)=1.909859317 inches.
What is the approximate circumference of a circle with a radius of 30 inches?
The exact answer is 2*30*pi = 60*pi Using 3.14 as an approx value for pi, the approx circumference would be 3.14*60 = 188.4 inches
How is the value of pi equals 3.142?
The circumference of a circle divided by the radius. (Works on any circle)
