Circumference: 12*pi = 37.699 cm rounded to three decimal places
The perimeter of a circle is its circumference
The circumference of a circle if the diameter is 12cm is 37.7cm
12pi cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
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
Using 3.14 as Pi the area of circle is: 113.03999999999999
The diameter of circle A is 12cm so its radius must be 6cm.

circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
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 radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
