I you mean a radius of 30" than it would be 60".
If you mean an area of 30" than it would be 19".
6.5 inches
Diameter = 30/pi inches
A circle with a 12 inch diameter has a 6 inch radius.
The circumference of 9 inch diameter circle is about 28.27 inches.
The circumference of a circle with a 39 inch diameter is 122.52 inches.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
Diameter = 30/pi inches
The circumference of every circle is (pi) x (diameter).The circumference of this particular circle is 30 pi.
30 inches; the radius of a circle is 1/2 its diameter.
If you mean perimeter length of a 30 inch diameter circle, then it is 30*Pi or 94.248 inches (rounded to 3rd decimal).
diameter of the circle = 30/pi = 9.549 inches to 3 dp
