The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius and π (pi) is approximately 3.14. Given a radius of 90 cm:
C = 2 * 3.14 * 90
C ≈ 565.2 cm
Therefore, the approximate circumference of a circle with a radius of 90 cm is 565.2 cm.
C = 2 * 3.14 * 90
C ≈ 565.2 cm
Therefore, the approximate circumference of a circle with a radius of 90 cm is 565.2 cm.

The circumference of a circle can be calculated using the formula: C = π * d, where d is the diameter of the circle. Given a diameter of 379 feet:
C = 3.14 * 379
C ≈ 1190.1 feet
Therefore, the approximate circumference of a circle with a diameter of 379 feet is 1190.1 feet.
The correct response is:
1190.1 feet
C = 3.14 * 379
C ≈ 1190.1 feet
Therefore, the approximate circumference of a circle with a diameter of 379 feet is 1190.1 feet.
The correct response is:
1190.1 feet
