Well, isn't that just a happy little question! To find the circumference of a circle, you can use the formula C = πd, where d is the diameter. So, for a 14-inch diameter circle, the circumference would be 14π inches. Just imagine that circle with its beautiful, perfectly measured edge - what a joy to calculate!
circumference = pi*diameter So diameter = circumference/pi = 14*pi = 4.46 cm
43.96
Circumference of 14 inch radius circle: 2*pi*14 = 28*pi inches or about 87.96 inches rounded to two decimal places
You need to understand the concept of the number pi. pi is the the number of diameters you can "wrap" around a circle. The number is 3.14... So if you had a circle with a diameter of 1 cm then the circumference would be 3.14 x 1 which equals 3.14 cm Since the diameter is 14 cm the circumference is 3.14 x 14 cm The equation that deals with this is ... circumference = pi x diameter or c=pi x D
the answer for the area is 615.8 and the answer for the circumference is 88 inches when you round!!!!
diameter = circumference/pi
The circumference of a circle 14' in diameter is about 43.98'
If a circle has a diameter of 14, the circumference is: 43.98.
The circumference of a circle with a diameter of 14 is: 43.982
Multiply the known diameter by the value of PI - and you'll have your answer !
The circumference of a circle with the diameter of 14 ft is: 44 feet.
If that's a circle, the diameter is 13.84648 inches.
circumference = pi*diameter So diameter = circumference/pi = 14*pi = 4.46 cm
A circumference of 43.98 units.
The circumference is approximately 43.98
It depends on what you mean by a "7-inch circle". If, as is normally the case, it is a circle with a 7-inch diameter, then you've got your answer in the question. If, unusually, you mean a circle with a 7-inch radius, then the diameter is twice that - 14 inches. If, even more unusually, you mean a circle with a circumference of 7 inches, then the diameter is 7/pi = 2.228 inches.
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches
