If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches

The answer will depend on what 15 dm represents: the radius, diameter or even circumference!

This is an easy calculation to do. Simply multiply the diameter by Pi (about 3.1416).15mm x 3.1416 = 47.124 mm circumference.

using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm

If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).

The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm

If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15

A circumference of 47.1'

Diameter = Circumference/pi = 14.99 cm

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.

About 4.712 inches.

15/pi so the diameter is about 4.8

15/pi = 4.77"

A circle's circumference is the product of Pi and its diameter, so a diameter can go around a circumference approximately 3.14 times.

diameter = 15pi/pi = 15 units in length

Circumference of the circle: 15 times pi = 47.1238898 meters

Its diameter is: 15'/pi = 4.775' rounded to 3 decimal places
