The circumference of a 4 inch round circle is: about 12.57 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
The round perimeter of circle is its circumference
47.25
If the circumference of the circle is 4 inches then the radius = 4/(2*pi) = 0.6366197724 inches And the area of the circle = pi*0.63661977242 = 1.273239545 or about 1.273 square inches
Circumference = Pi * diameterAssuming the "32 inches" mentioned above is the diameter of the circle (and using pi equals 3.14 as a very rough estimate) then the circumference is approximately:3.14 * 32 = 100.48Thus to the nearest option above it is 100 inches.
The circumference of a 24-inch round (diameter) circle is: 75.4 inches.
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?"
The circumference of a 4 inch round circle is: about 12.57 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
circumference is the distance around the circle, so it sounds as though you are stating the circumference in your original question; 66 inches.
The round perimeter of circle is its circumference

diameter = circumference/pi = 12/pi inches
If the circumference of the circle is 4 inches then the radius = 4/(2*pi) = 0.6366197724 inches And the area of the circle = pi*0.63661977242 = 1.273239545 or about 1.273 square inches
Circumference = Pi * diameterAssuming the "32 inches" mentioned above is the diameter of the circle (and using pi equals 3.14 as a very rough estimate) then the circumference is approximately:3.14 * 32 = 100.48Thus to the nearest option above it is 100 inches.
The circumference of a 12-inch round circle in pi is: 12pi
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
Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699 Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
