The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is given as 80 inches. Plugging this value into the formula, we get C = π(80) = 251.327 inches. Therefore, the circumference of the circle with a diameter of 80 inches is approximately 251.327 inches.
Diameter of a circle = circumference/pi
25.464
A circle with a radius of 80 inches has a circumference of 502.65 inches, which is equal to 41.8875 feet. Therefore, it is greater than a circle with a circumference of 40.5 feet.
Circumference = π*d = π*80 = 251.33 units
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 diameter of 80 meters, the circumference is ( C = \pi \times 80 \approx 251.33 ) meters. Thus, the circumference is approximately 251.33 meters.
