radius = b/2*pi
Circumference of a circle = pi*diameter or 2*pi*radius
find the radius of a circle with circumference of 42.1
For a circle, circumference = 2 x pi x radius.
The circumference of a circle is twice the radius times PI [2*pi*r] with r = 4 >> about 25
A circle with a radius of 8 inches has a circumference of 50.27 inches.
Circumference of a circle = 2*pi*radius
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Circumference of a circle = 2*pi*radius Circumference = 2*pi*5.6 = 35.18583772 units
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
To find the radius of a circle, divide the circumference by 2π (approximately 6.28). Therefore, the radius of the circle with a circumference of 232.4 inches is 36.9 inches (232.4 / 6.28).
Circumference of a circle = 2*pi*radius or diameter*pi
