It does not have a circumference but its perimeter is: 4+6+8 = 18 cm

The formula for the circumference of a circle is C = 2Ï€r, where C is circumference, Ï€ 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

12cm x 6cm x 4cm = 288 cubic centimetres

20 cm

The circumference of a circle = 2*pi*radius or diameter*pi

The formula for the circumference of a circle is C = 2Ï€r, where C is circumference, Ï€ 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.

16 cm

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

C = ~37.7 cm A = ~113.1 cm2

Circumference = 2 pi R = 12 pi = 37.7 cm(rounded)

12cm x 6cm x 4cm = 288 cubic centimetres

20 cm

It means the distance from the centre of the circle to its circumference (or boundary) is 6 centimetres or 0.06 metres.

A=1/2(b)(h). So A=1/2(6cm)(4cm). A=12cm^2, or 12 squared centimeters.
