What is the ratio to any circles circumference to the diameter?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
What is the circumference of a circle when the area is 36 pi?
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
What is the circles diameter if the circumference is 12.56?
diameter = 12.56/pi
What is the area of a circle with a circumference of 88cm?
Circumference = 2*pi*r where r is the radius so Radius = Circumference/(2*pi) and then Area = pi*r2 So, circumference = 88 cm implies that area = 616.25 cm2
What is the circumference and area when radius 9in and d 7.3?
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What is the area of a circles with a circumference of 22?
Using 3.14 as Pi the area of circle is: 0
What is the answer to circles and circumference?
circumference = 2*pi*radius or pi*diameter
How does pi relate to the circumference and diameter of a circle?
pi = circumference divided by diameter
How is pi used to find the circumference of circles?
Circumference of any circle = 2*pi*radius or pi*diameter
How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
What is the surface area of 3.14?
3.14 is a constant . It has no surface area. It is an approximation for pi = 3.141592.... 'pi' is the ratio between a circles circumference and its diameter. C = pi*d
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
How do you find the circumference when you have the area?
If you are talking about circles determine the radius by dividing the Area by pi and take the square root of the result. Then multiply the radius by two times pi.
How do you find the circumference of circles?
The circumference of a circle = pi*diametre = 2pi*radius
What are the formulas for circumference and area of circles?
The circumference ( C ) of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). In both formulas, ( \pi ) (pi) is a constant approximately equal to 3.14159.
How do you put something in terms of pi?
To express a quantity in terms of pi, you need to relate it to a circular measurement, such as the circumference or area of a circle. For example, if you have the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius, to express the circumference as a multiple of pi. Similarly, for the area, use ( A = \pi r^2 ) to express the area in terms of pi. Simply factor out pi from the equation to achieve the desired expression.
