circumference
r, for radius
yes, it varies with the length of the radius. Pi is the only constant of circle math.
The formula for circumference is Pi x D= Circumference. If you know the circumference you solve for the diameter as you would any other variable. Let's say the circumference is 10, the equation would then be: Pi (3.14) x D = 10. Solve for D. D= 10/3.14
1 meter is one forty-millionth of the polar circumference of Earth.
A circumference is 4
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
THE FORMULA FOR FINDING THE CIRCUMFERENCE IS:CIRCUMFERENCE EQUALS DIAMETER TIMES 3.14In basic words:What do you know?You know you need to find the circumference of the circle, which is the distance all the way around the circle.You know the radius is 25 inches, the radius is the measurement from the center to the circumference of the circle.You know the formula needs the diameter, a diameter being the length of a line connecting two points on the circumference, touching the center of the circle, maintaining a straight line.With all this information, you can figure out that the radius is half the diameter.Now, begin your math.Problem: What is the circumference of a circle when you know the radius is 25 inches?Formula: Circumference= Diameter X 3.14 which is known as pi.Radius Diameter CircumferenceR=25 D=R times 2Replace variable R with the correct number:2525 multiplied by 2 is 50 which means that D=5050 multiplied by 3.14 is 157The circumference is 157
To convert area into circumference, take the two formulas for circles--circumference and area: C=2pi*r A=pi*r^2 Now, isolate the common variable (r) in the second equation. r=sqrt(A/pi) Now you can substitute this in for "r" in the first equation to find circumference C=2pi*sqrt(A/pi) C=2pi*sqrt(36pi/pi) pi cancels out C=2pi*sqrt(36) C=2pi*6 C=12pi
circumference=pi circumference=pi circumference=pi
Yes it is. Linear simply means that the degree (or number of powers) of the variable is 1. In this case the variable is the radius "r" and it occurs to the first power ... so the equation C=2 times pi times r is linear in r. Ralph the triangle
pi is a letter in the greek alphabet (π) which in math represents the irrational number value of 3.141592653589793238462... we use pi as a variable instead of writing out the endless decimal everytime it is used. By this, we can calculate the area and circumference of circles, you can find the area by πr2 which r is the radius or radii, and to find the circumference it is 2πr.
