The radius of a circle with a circumference of 1000m is approximately 159.15 meters. This can be found using the formula C = 2πr, where C is the circumference and r is the radius. Rearranging the formula to solve for r gives r = C / (2π). Substituting the given circumference into the formula will give you the radius.
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
The circumference of a circle with a radius of 3.2 cm is approximately 20.1 cm. This can be calculated using the formula: circumference = 2 * π * radius.
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
The formula for the circumference of a circle is C = 2πr, where r is the radius. Substituting 8.1 for the radius, we get C = 2 * π * 8.1 ≈ 50.92. Therefore, the circumference of the circle is approximately 50.92.
This is the radius of the circle. It connects the center of the circle to any point on the circumference. The length of the radius is constant for a given circle.
