The circumference of a circle with a diameter of 45 inches is 141.37 inches.
The circumference of a circle can be calculated using the formula (C = \pi \times d), where (d) is the diameter. For a circle with a 45-inch diameter, the circumference would be (C = \pi \times 45 \approx 141.37) inches. Therefore, the circumference of a 45-inch diameter circle is approximately 141.37 inches.
37 45/64 inches.
To find the diameter from the circumference, you can use the formula: diameter = circumference / π. For a circumference of 4.59 inches, the diameter would be approximately 4.59 / 3.14, which equals about 1.46 inches.
The diameter of a circle with a circumference of 2.75 inches is: 0.875 inches (circumference divided by pi = diameter).
