The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).
The formula for finding the circumference is the diameter times pi because the radius is half of the diameter, the diameter of this circle would be 8 8 times pi equals approximately 25.1327 Or you could leave it in terms of pi and say 8pi (using the symbol)

4 + 8 = 12 is correct.
Diameter = 2*Radius

An impossibility but 4 out of 5 equals 80% of the questions were correct
You have to understand that two radius makes up a diameter. That means if given the radius you can just times it by 2 to get the diameter 4 cm= 8cm diameter
