It is very easy math!
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
A circle with a radius of 81 cm has a circumference of 508.94 cm
Circumference=20.1 cm.
The diameter of a circle if the circumference is 41 cm is about 13.05 cm (C divided by Pi = diameter)
If the radius of a circle is 15 cm, the circumference is: 94.2 cm
A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
circumference = 15*pi = 47.124 cm rounded to 3 dp
circumference = 15*pi cm
Circumference of a circle = 2*pi*radius or diameter*pi
Its circumference is: 15*pi cm Its area is: pi*7.5^2 square cm
566cm
There are various ways of measuring circles, since a circle has a radius, a diameter, and a circumference, so your question asking how to divide a circle to 15 cm is not as precisely stated as it might be. You can use a segment of a circumference to get 15 cm, by taking the appropriate wedge out of the circle, but even then, unless we know what the radius of the circle is, we cannot tell you what angle is needed to obtain the wedge you want, with a 15 cm circumference.
To find the diameter of a circle with a given circumference, you can use the formula: circumference = π * diameter. Given a circumference of 47.1 cm, you can rearrange the formula to solve for the diameter. Divide the circumference by π (approximately 3.14159) to find the diameter. Therefore, the diameter of a circle with a circumference of 47.1 cm is approximately 15 cm.
