The formula for circumference is
c = pi*diameter
and the formula for area is
a = pi*r^2
Therefore, the circumference is 9.3*pi
and the area is pi*(4.65)^2
*4.65 since the radius is half the diameter*
*You could substitute pi with 3.14, though leaving your answers in terms of pi is better*
There is no such thing as an "area of circumference".If 27 cm is the diameter, you can calculate the circumference by multiplying this by pi, which is approximately 3.1416.
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.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
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 = pi*diameter
The diameter is 29.6
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
The base has a circumference of 93 miles
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
There is no such thing as an "area of circumference".If 27 cm is the diameter, you can calculate the circumference by multiplying this by pi, which is approximately 3.1416.
If you mean a circle with a 93 inch diameter - it will have a 46.5 inch radius, giving it an area of ~6792.909 sq inches = ~47.173 sq ft. If you mean a circle with a 93 inch circumference - that will have a diameter of ~29.6 inches (radius of ~19.8 inches) and an area of ~688.3 sq inches = ~4.78 sq ft.
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
