A=pi*radius2=pi*(diameter/2)2
A=pi*(45/2)2 = 1589.625 square feet if pi=3.14
A 45-foot diameter circle has an area of 1,590.4 square feet.
Using 3.14 as Pi the area of circle is: 6358.500000000001
Area of circle = Pi x diameter2/4 = 3.142 x 49/4 = 38.49 sq ft
A 45-foot circumference circle has an area of: 161.1 square feet.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
A 45-foot diameter circle has an area of 1,590.4 square feet.

A 45-foot circumference circle has an area of: 161.1 square feet.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a 12-foot-diameter circle is 37.7 feet.
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
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.
