What is the approximate circumference of a circle that has a radius of 90?
The approximate circumference of a circle with a radius of 90 can be found using the formula:
C = 2πr
where r is the radius of the circle and π is a mathematical constant equal to approximately 3.14.
C = 2π(90)
C ≈ 565.48
Therefore, the approximate circumference of a circle with a radius of 90 is 565.48.
The circumference of a circle can be found using the formula C = 2πr, where C is the circumference, and r is the radius.
For a circle with a radius of 90, the approximate circumference would be:
C = 2π(90) ≈ (2)(3.14)(90) ≈ 6.28 * 90 ≈ 565.2
Therefore, the approximate circumference of a circle with a radius of 90 is 565.2 units.
