It is: 2 to 3 respectively
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 = 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
12cm x 6cm x 4cm = 288 cubic centimetres
20 cm
The circumference of a circle with a diameter of 6cm is about 18.85cm
It does not have a circumference but its perimeter is: 4+6+8 = 18 cm
The circumference of a circle = 2*pi*radius or diameter*pi
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.
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
The perimeter of a rectangle is calculated by adding up the lengths of all four sides. In this case, the rectangle has two sides of length 6cm and two sides of length 4cm. Therefore, the perimeter would be 6cm + 6cm + 4cm + 4cm = 20cm.
It means the distance from the centre of the circle to its circumference (or boundary) is 6 centimetres or 0.06 metres.
