Area = Pi/4 x d2 = Pi/4 x 144 cm. = 113.0973 sq.cm. (to nearest 4th decimal)
The circumference of a circle with a diameter of 12 cm is: about 37.7 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
Well, honey, if the diameter is 12 cm, all you gotta do is cut that bad boy in half to get the radius. So, the radius would be 6 cm. Easy peasy lemon squeezy!
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
