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
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
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
Diameter = 80/pi feet
The diameter is about 25.464 units.

80/pi = 25.465 cm (rounded)
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
divide it by three. that gets it close.
Circumference = Pi x d: 3.14 x 80 = 251.2 feet
