The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π x diameter. In this case, the circumference is 37.68cm. So, 37.68 = π x diameter. To solve for the diameter, you would divide 37.68 by π, which is approximately 3.14. Therefore, the diameter of the circle would be approximately 12 cm.

The circumference of circle with radius 12cm is 75.4cm
The circumference of a circle if the diameter is 12cm is 37.7cm

12pi cm
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
Circumference: 12*pi = 37.699 cm rounded to three decimal places
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
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
C=3.14D C=12x3.14 C=37.7+12=49.7
2(pi)r=2X3.14X3cm=18.85cm to four significant figures
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
