Circumference: multiply the diameter by pi (approximately 3.1416).
Area: Divide the diameter by 2 to get the radius. Then use the formula area = pi x r2, where r is the radius.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
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 area and circumference of a circle with a diameter of 55 centimeters
the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
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 circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2
