The formula for circumference is 2nr.
First we need to find 'r' which stands for radius (the straight distance from the centre of the circle to the edge). Since the radius is half of the diameter, the radius is 70/2=35 yds.
Now we can put 35 yds into the formula: 2*n*35 = 219.91 yds (rounded to 2 decimal places).
diameter = 70/pi
Circumference = 70*pi yards
A circumference of 219.91 units.
Approximately 22.3
Circumference = 2*pi*rr = diameter/2 = 70/2 = 35 yards2*pi(35 yards)= 220 yards in circumference===================
diameter = 70/pi
The diameter is about 22.3
Circumference = 70*pi yards
Circumference = 70*pi units of measurements
A circumference of 219.91 units.
Circumference of any circle = (pi) x (diameter) Circumference of this particular circle = (pi) x (70 yd)
Approximately 22.3
70/pi = a diameter of 22.28169203 units
Circumference = 2*pi*rr = diameter/2 = 70/2 = 35 yards2*pi(35 yards)= 220 yards in circumference===================
Diameter = 70/pi = 22.282 cm rounded to three decimal places
220 yards
I presume you mean the circumference in feet. Use the equation C = pi d C = 3.141592.... X 70 ft C = 219.9114858.... feet. ~ 219 ft 11 inches.
