The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
If the diameter is 12 cm the radius is 6 cm.
Radius of a circle is half of its diameter and so 12/2 = 6 cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
12*pi
6 cm. The radius is 1/2 of the diameter.
really!? Its 6 cm!
12 cm.
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
36*pi
12 cm
It is: pi*12*12 square cm
