If you want to find the area of a circle in cm you must find out the diameter and times it by Pi (3.14). That's all you have your answer
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
circumference = 6*pi cm
314.29 cm
The circumference of a circle with an 81.6 cm diameter is: 256.4 cm
If you want to find the area of a circle in cm you must find out the diameter and times it by Pi (3.14). That's all you have your answer
10 cm
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
37.7 cm
circumference = 6*pi cm
If the diameter is what you are talking about that is 6 cm, you must divide that number by two to find the radius because the radius is half a diameter. The radius of a circle with a diameter of 6 cm. would be 3 cm.
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
314.29 cm
Circumference = 2*pi*15.5 in cm
A circle with an area of 200.96 cm2 has a:Radius of about 8 cmCircumference of about 50.25 cm
