The circumference of a circle = 2*pi*radius or diameter*pi
The circumference of a circle with a diameter of 6cm is about 18.85cm
Circumference = 2 pi R = 12 pi = 37.7 cm(rounded)
Circumference of a circle is 2πr (two x Pi x the radius of the circle)Pi is usually taken as 3.14 for simple calculations - see here http://en.wikipedia.org/wiki/Pi for a longer determination of Pi.The radius is half the diameter.Thus, a circle with a diameter of 6cm has a circumference of 18.84cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
Since it'll be rolling around the outside of the circle, the distance traveled will be in some multiple of the circumference. So, dividing the distance by the circumference will give the answer. C = πD = 6π revolutions = distance / circumference = 108π / 6π = 18 revolutions
The circumference of a circle with a diameter of 6cm is about 18.85cm
It is: 2 to 3 respectively
The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
C = 2πr π = 3.142, r = 6cm C = 2(3.142x6)cm C = 41.04cm
It does not have a circumference but its perimeter is: 4+6+8 = 18 cm
Circumference = 2 pi R = 12 pi = 37.7 cm(rounded)
C = ~37.7 cm A = ~113.1 cm2

It means the distance from the centre of the circle to its circumference (or boundary) is 6 centimetres or 0.06 metres.
6cm + 6cm = 12cm
6cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
