A=pi r^2 A=(3.14)(7^2) A=(3.14)(49) A=153.86 feet
find the radius of a circle with circumference of 42.1
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
A circle with a radius of 8 inches has a circumference of 50.27 inches.
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.
You have to find the diameter, 12, then you have to multiply that by 3.14 or pi... which equals 37.68.
find the radius of a circle with circumference of 42.1
The circumference of a circle is calculated by multiplying the diameter of the circle by Pi. Multiply the radius by 2 to find the diameter. The diameter is 125.6. Now multiply it by Pi. (Pi equals 3.14) This makes the circumference of the circle 394.38.
For a circle, circumference = 2 x pi x radius.
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
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.
You have to find the diameter, 12, then you have to multiply that by 3.14 or pi... which equals 37.68.
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
The circumference of a circle equals 2 times pi times the radius, in this case, about 31.42 inches.
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).
