Oh honey, let me break it down for you. The diameter of a circle with a circumference of 27cm is about 8.59cm. You just take the circumference and divide it by π (that's pi for you math newbies). So there you have it, simple as pie... or should I say, simple as pi!
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)
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.
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)
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
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
Circumference = 27 cm So radius, r = 27/Pi = 4.297183 cm Then surface area = 4*Pi*r2 = 232.05 cm2
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)
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 is about: 44 Area is about: 153.94
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 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
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 football is 27cm in long and 60 cm in circumference.
