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
How do you calculate the circumference of a circle if you have the area is 8.2 com squared?
To calculate the circumference of a circle from its area, first use the formula for the area ( A = \pi r^2 ). Given that the area is 8.2 cm², you can solve for the radius ( r ) by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). Once you find the radius, use the circumference formula ( C = 2\pi r ) to calculate the circumference.
What is the circumference and the area for cm?
To calculate the circumference and area of a circle, you need the radius (r) or diameter (d). The circumference (C) is given by the formula ( C = 2\pi r ) or ( C = \pi d ). The area (A) is calculated using the formula ( A = \pi r^2 ). If you provide the radius or diameter in centimeters, I can give you the specific values for circumference and area.
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 area circumference?
Area = (Circumference)2/(4*pi)
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)
