The circumference (C) of a circle is given by the formula C = 2πr
But, the diameter equals twice the radius so we can write C = πd....where d is the diameter.
So, C = 40π = 125.664 (3dp)
D = ~12.73 cm
circumference = pi*40cm
Diameter of a circle = circumference/pi
If the circumference of a circle is 17.27, the diameter is: 5.5
The diameter of a circle with the circumference of 3.25 is: 1.034
D = ~12.73 cm
circumference = pi*40cm
Circumference is equal to πd and therefore is 22/7 ×40=125 whole number and 5 all over 7
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
A circle with a circumference of 11.25 has a diameter of: 3.581
The circumference of a circle with a diameter of 25 is: 78.54
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 14, the circumference is: 43.98.
If a circle has a diameter of 2.25, the circumference is: 7.069
If the circumference of a circle is 17.27, the diameter is: 5.5
