Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
A 45-foot circumference circle has an area of: 161.1 square feet.
If the radius of the circle is 1, the area is pi. (3.14159 square units) The circumference is twice that. (6.28318 units)
About twice in square units If the circumference of a circle is about 25.12 units, the area will be about 50.21 square units.Given: circle with circumference C = 21.12Sought: Area of circleC = 21.12Diameter d = C / π>> d = 21.12 / 3.14159 ≈ 8Radius r = d / 2>> r = 8 / 2 = 4Area A = π r2>> A = 3.14159... × 4 ≈ 50.2145...
Pressure equals force divided by area.
The circumference is 4pi
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
The circumference of any circle divided by its diameter is always equal to pi. With this information we can work out various properties of the circle such as its circumference or its area.
The radius of a circle is the distance from the centre of the circle to a point on the circumference of the circle. If it is a drawing and the circle is to scale the radius can be measured with a ruler. If not, the radius can be calculated if the diameter, circumference or area of the circle is known. the radius is equal to: - the diameter divided by 2 - the circumference divided by 2pi(approx. 6.284) - the square root of the area divided pi (divide by pi first, then take the square root)
You dived the area by the circumference of the circle.
The area of a circle with a circumference of 9.42 is about 7.06.
Area = Circumference squared divided by 4pi.
No,Circumference is like the perimiter and Area is the whole circle.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
