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.

Well, darling, if the diameter of a circle is 80 inches, then the radius is half of that, which is 40 inches. The circumference of a circle is calculated using the formula C = 2πr, so plug in the radius and you get C = 2 x π x 40 inches, which simplifies to a sassy 80π inches.
Diameter of a circle = circumference/pi

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
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
