Circumference = pi*d
Area = pi*d2/4
So 4*area = pi*d2
4*area/Circumference = pi*d2/(pi*d) = d

What are 3 formulas you can use for finding a circumference?
Given diameter = d: circumference = pi*d Given area = a: circumference = 2*sqrt(pi*a) Given an arc of length L subtends an angle x degrees at the centre: circumference = 360*L/x
What is the formuls for finding the circumference?
It depends on what information you have: radius, diameter, area, etc.
What is the formula of finding the area with a given circumference?
3.14 to the 2 power
What does pi have to do with the area and circumference of a circle?
It is used in finding the circumference and area of a circle. Circumference = 2*pi*radius or pi*diameter measured in linear units Area = pi*radius2 measured in square units
If 2.5 is the diameter then what is the radius?
Radius is 1/2 of a diameter. 2.5/2 is 1.25. Radius is necessary in finding the circumference and area of a circle.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What are 3 formulas you can use for finding a circumference?
Given diameter = d: circumference = pi*d Given area = a: circumference = 2*sqrt(pi*a) Given an arc of length L subtends an angle x degrees at the centre: circumference = 360*L/x
What is the formula for finding the radius?
The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
If the area of a circle is given as 67cm squared find the diameter and then circumference of this circle?
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
What is the formuls for finding the circumference?
It depends on what information you have: radius, diameter, area, etc.
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What is the formula of finding the area with a given circumference?
3.14 to the 2 power
Area of a circle with a 12 inch circumference?
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
What does pi have to do with the area and circumference of a circle?
It is used in finding the circumference and area of a circle. Circumference = 2*pi*radius or pi*diameter measured in linear units Area = pi*radius2 measured in square units
If 2.5 is the diameter then what is the radius?
Radius is 1/2 of a diameter. 2.5/2 is 1.25. Radius is necessary in finding the circumference and area of a circle.
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
