The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
Circumference = Pi X Diameter = 3.1415 X 4cm = 12.566cm
It is: 2 to 3 respectively
circumference of the circle = 4*pi cm
C = 12.6 cm
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
Circumference = Pi X Diameter = 3.1415 X 4cm = 12.566cm
A circumference of 12.57 cm
It is: 2 to 3 respectively
circumference of the circle = 4*pi cm
C = 12.6 cm
The formula for the circumference of a circle is C = πd, π = 3.142, d = 4cm C = 3.142 x 4cm C = 12.568cm
4 times pi. That is about 12.57.
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
About 12.56 cm Btw the formula is diameter x pi (3.14)
There are an infinity of points 4cm from a given line. These points form 2 lines parallel to and either side of the original line. Equally, there are an infinite number of points 4cm from a given point on the original line. These points lie on the circumference of a circle radius 4cm with its centre at the given point. There are only 2 points that fulfil both conditions. These points are found on the circumference of the circle where a diameter perpendicular to the original line and passing through the given point meets the circumference of the circle. These two points are also where the two parallel lines form tangents with the circle.
Circumference of a circle is C=2pir C=2pi(4) C=8pi C=25.12 cm Where pi is the ratio of the circumference to the diameter of any circle, approximately 3.14. There is usually a button for pi on scientific/graphing calculators.
