Finding the diameter if given the circumference and area?
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
What is the formula to be used if the diameter is given?
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.
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 are the difference of circumference formula and area formula?
Circumference is the distance around the object and Area is the amount of space it takes up.
What is the formula for the volume of a sphere in terms of surface area S?
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
Formula for finding radius of a circle?
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
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 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.
What is the formula of finding the circumference of a sphere?
4*pi*r2. because surface area is equal to circumference of circle.
Finding the diameter if given the circumference and area?
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d

If the area of a circle is 201.06 then the circumference of the circle is?
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.
What is the area of a circle with a circumference of 56.52 inches?
To find the area of a circle when given the circumference, you can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is pi (approximately 3.14159). Plugging in the given circumference of 56.52 inches, the formula becomes A = (56.52^2) / (4 * 3.14159), which simplifies to A ≈ 159.05 square inches. Therefore, the area of the circle with a circumference of 56.52 inches is approximately 159.05 square inches.
What is the formula for finding the area of base of a cylinder?
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)
What is the formula for circumference?
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.
What is the formula for area circumference?
Area = (Circumference)2/(4*pi)
