30/pi = just over 9.5 cm
The circumference of a circle 30 inches in diameter is 30*pi inches
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units.
The circumference of a circle with diameter of 30 centimeters is: 94.2 cm (diameter x Pi = circumference).
The circumference of every circle is (pi) x (diameter).The circumference of this particular circle is 30 pi.
the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46
diameter = 30/pi units of measurement
Diameter = 30/pi inches
Circles are most simply and commonly specified by their diameter. So a 30 foot circle has a diameter of 30 feet.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
The radius if the circle is half of its diameter and so 30/2 = 15 mm
You need to qualify the 30 inches. Is it the diameter or circumference of a circle?
