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 = ~37.7 cm A = ~113.1 cm2
It is: 2 to 3 respectively
The radius of a circle, if the circumference is 188.5, is 30.
The radius of a circle with the circumference of 19.96 is about 3.18
A circle with a radius of 3.1cm has a circumference of 19.48cm
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
C = ~37.7 cm A = ~113.1 cm2
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
Circumference = 2 pi R = 12 pi = 37.7 cm(rounded)
It means the distance from the centre of the circle to its circumference (or boundary) is 6 centimetres or 0.06 metres.
The answer depends on what the "6cm" refers to.
It is: 2 to 3 respectively
The circumference of circle with radius 12cm is 75.4cm
The circumference of a circle if the radius is 29 is about 182.21
The radius of a circle with a circumference of 110 is: 17.507
The circumference of a circle with a radius of four is: 25.13
