The circumference of a circle is calculated using the formula 2πr, where r is the radius of the circle.

Circumference = 2 * 3.14 * 70
Circumference = 2 * 3.14 * 70
Circumference ≈ 439.5

Therefore, the approximate circumference of a circle with a radius of 70 is approximately 439.5.

The circumference of a circle is calculated using the formula πd, where d is the diameter of the circle.

Given that the diameter is 412, we can calculate the circumference:
Circumference = π * 412
Circumference = 3.14 * 412
Circumference ≈ 1293.68

Therefore, the approximate circumference of a circle with a diameter of 412 is approximately 1293.68.
