Hi there!
So first to find the diameter, you will need to find the radius of the circle because the diameter is twice the length of the radius.
Find the radius from the circumference, which is
.
C=
212=
212/
=r
Then solve for r.
Radius= 33.74
Then multiply the radius by 2 to find the diameter.
Diameter= 2 * 33.74
Diameter= 67.5 inches
Hope this helps :)
