The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
A circumference of 47.1'
Circumference of the circle: 15 times pi = 47.1238898 meters
15 pi feet
It is 15 times pi in inches
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
A circumference of 47.1'
Circumference of the circle: 15 times pi = 47.1238898 meters
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.
Diameter = Circumference/pi = 14.99 cm
You've stated an impossible question. If a circle has a circumference of 94.2 cm, it has a diameter of 30 cm. If it has a diameter of 15cm, it has a circumference of 47.1 cm.circumference = 2 * pi * radius = pi * diameterIf you had stated the question correctly (changed circumference to 47.1 cm OR changed diameter to 30 cm OR changed "diameter" to "radius"), then the answer would be:pi = circumference / diameter = (e.g.) 94.2 cm / 30 cm
566cm
About 4.712 inches.
15 pi feet
diameter = 15pi/pi = 15 units in length
It is 15 times pi in inches
