It is twice its radius
is it a pencil.
Circumference of the circle: 23*pi = 72.257 inches rounded up to 3 decimal places
A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
curcumference should be about 9.42 3 inch diameter If the ball diameter is 3 inches, then the surface area is Pi x D2 = Pi x 9 = 28.274 square inches (rounded to third decimal).
The circumference of a circle with a 6-inch diameter is 18.85 inches. (C = d x Pi).
diameter = 26/pi = 8.276057041 or 8.276 inches to 3 decimal places
diameter = 26/pi = 8.276057041 or 8.276 inches to 3 decimal places
Diameter: 87.5/pi = 27.852 inches to 3 decimal places
Remember the circle equation C = pi d To find 'd' the diamter , algebraically rearrange . d = C/ pi d = 6 incnhes/ 3.141592.... d = 1.9098593147.... inches d ~=~ 1.9 inches
Diameter of circle: 4.25/pi = 1.353 inches rounded to 3 decimal places
Diameter of circle: 2.5/pi = 0.796 inches rounded to 3 decimal places
If its diameter is 26 inches then its circumference = 26*pi = 81.681 inches to 3 decimal places
If its diameter is 14 then its area is: pi*72 = 153.938 square inches to three decimal places
If the circumference is 37 inches then the diameter is 37/pi = 11.78 inches rounded to two decimal places
circumference = pi x diameter. So rearranging gives diameter = circumference / pi So diameter = 6/pi = 1.9 inches (1 decimal place)
Circumference: 29*pi = 91.106 inches to 3 decimal places
The diameter is: 74/pi = 23.555 inches rounded to 3 decimal places
