Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
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
To find the circumference of a circle with a given area, you first need to calculate the radius. Since the area of the circle is 27 acres, you can use the formula A = πr^2 to solve for the radius. Once you have the radius, you can then find the circumference using the formula C = 2πr. By substituting the radius into the formula, you can calculate the circumference of the 27 acre circle.
Circumference is the distance around the object and Area is the amount of space it takes up.
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
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.
4*pi*r2. because surface area is equal to circumference of circle.
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
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
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
There are 2 formulas for finding the circumference of the circle.If the radius diameter is given,we use the formula �d.When the radius is given,we use the formula 2�R. * * * * * But there are also other formulae for when the area is given, or the length of an arc and the angle subtended at the centre or on the circumference are known. Plus many more. Basically, the question is too poorly specified to find a single answer. Also, the above formulae assume that the shape is a circle. But it could be an ellipse, for example.
Area = (Circumference)2/(4*pi)
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
