Area of the circle in square cm = pi*radius2
If the circumference of a circle is 12 cm the radius is: 1.91 cm
A circle with a radius of 0.5 cm has a circumference of 3.14 cm.
A circle with a radius of 208 cm has a circumference of 1306.9 cm
A circle with a radius of 9.2 cm has a circumference of 57.81 cm
Area of the circle: pi*20*20 = 400*pi square cm
Area of the circle in square cm = pi*radius2
If the radius of a circle is 2.5 cm, then its diameter is 5 cm long.
If the radius of a circle is 2.5 cm, then its diameter is 5 cm long.
10cm or 0.05meters
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
The radius of the circle is: 9.549 cm
The area of a 3 cm circle is: 7.069 square cm
The radius of a 2 cm circle is: 1 cm
The circumference of a 12 cm circle is: 37.7 cm
10 cm
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
