Oh honey, it's simple math. The circumference of a circle is found by multiplying the diameter by pi (π). So, if you have the diameter in centimeters, just multiply it by 3.14159 to get the circumference in centimeters. Easy peasy lemon squeezy!
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
