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)
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985
what is the area and circumference of a circle with a diameter of 55 centimeters
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
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Circumference is about: 44 Area is about: 153.94
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 = 27 cm So radius, r = 27/Pi = 4.297183 cm Then surface area = 4*Pi*r2 = 232.05 cm2
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
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 .
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
