Circumference = 2*pi*r
Radius = diameter/2
r = 20 cm/2 = 10 cm
-------------------------
Circumference = 2*pi(10 cm)
= 63 centimeters

Diameter in cm = circumference/pi
Circumference of the circle = pi*17.6 cm
It has a circumference of 12.88 cm
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given that the circumference is 4.4 cm, you can plug this value into the formula: 4.4 = π * diameter. To solve for the diameter, divide both sides by π, resulting in diameter ≈ 1.4 cm. Therefore, the diameter of the circle is approximately 1.4 cm.
Circumference of the circle = pi*17.6 cm
