The equation for the circumference of a circle is C=2 x pi x radius
We also know that the radius is always half of the diameter. So in this case since the diameter is 42.5, the radius is 21.25.
So plugging the numbers in the circumference is:
C= 2 X 3.14 X 21.25= 133.45
Hope this helps!

How do you get diameter from circumference?
Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
If you have your circumference how do you find the diameter?
diameter = circumference/pi
WHats the diameter of a circle with a circumference of?
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
What is the diameter of a circle with the circumference of 5?
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
Is there a relationship between the circumference and the diameter of a circle?
Yes because: circumference/diameter = pi and circumference = pi*diameter
