Circumference of circle = 2 x pi x r where r is the radius. So we have here
120 = 2 x pi x r or
60 = pi x r or
60 = 3.1415 x r, Hence r = 60/3.1415 = 19.099
Area of circle is pi x r x r, here it is 3.1415 x 19.099 x 19.099 = 1145.93 square feet
The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
Circumference of a circle is pi multiplied by the diameter. If the diameter of the circle is 11 ft, the circumference is: 3.14 x 11 ft = 34.54 ft
The circumference of a circle with a diameter of 10 ft is: 31.42 feet (diameter x Pi = circumference).
The circumference of a 13-foot diameter circle is: ~40.84 ft
The circumference and area of a circle with a 17 ft diameter are:C = 53.4 ftA = 227 ft2
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
Using 3.14 as Pi the area of circle is: 0
Area of a circle = pi*radius2
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.

A 45-foot circumference circle has an area of: 161.1 square feet.
Circumference = 2 * pi * radius 12 pi ft = 2 pi radius radius of the circle = 6 ft Area = pi *radius2 Area = pi (6)2 Area = 36 pi ft2
The circumference of a 30 ft circle is: 94.2 feet.
The circumference of an 8 ft circle is: 25.1 feet.
The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.
