C = ~37.7 cm
A = ~113.1 cm2
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.
It is: 2 to 3 respectively
It depends on the relationship between the rectangle and the circles.
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
A ≈ 28.27cm2
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.
The circumference of a circle with a diameter of 6cm is about 18.85cm
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.
Area = pi*62 = 113.097 square cm to 3 dp
It is: 2 to 3 respectively
It depends on the relationship between the rectangle and the circles.
12 cm.
6/2 = a radius of 3 cm
