The diameter of a circle or sphere is the length of a straight line that touches both sides and passes through the centre.
3.14 x 12.52 = 490.625 or round it up to 490.63 millimeters.
If 34 inches is the radius or diameter of the circle, (or circumference?), it needs to be stated in the question! What is meant by "round circle?"
diameter = circumference/pi = 12/pi inches
Radius is the distance from the centre of a circle to the outside The circumference of a circle is the distance round the outside of a circle
It is round and the circumference is 3.14 times the diameter.
A circle with a diameter of 11 inches has an area of 95.03 square inches.
The circumference of a circle is calculated using the formula C = ฯd, where C is the circumference, ฯ is a mathematical constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter of the circle is 24 inches. Therefore, the circumference of a 24-inch round circle would be C = ฯ * 24 = 75.398 inches.
If the circumference of the circle is 2.5 inches then its diameter is 2.5/pi = 0.796 of an inch rounded up to 3 decimal places
You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
Diameter of the circle: 31.4/pi = 10 miles rounded up
The diameter of a circle is twice its radius and spans the circle passing through its centre.
