5,541.77 square cm.
In any circle, the ratio of circumference to diameter is (pi).
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
Work it out the circumfrance of a circle is pie x the diameter!
3.9 x 3.14 m
A diameter of 84cm, means the circle is 84cm wide. A diameter is a line or measurement from one edge, through the centre, to the opposite edge of the circle.
The diameter should be 7m.
5,541.77 square cm.
In any circle, the ratio of circumference to diameter is (pi).
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
circumference of a circle = pi*diameter or 2*pi*radius
Work it out the circumfrance of a circle is pie x the diameter!
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
3.9 x 3.14 m
Pi (3.14) × the diameter Therefore, 3.14 x 2 = 6.28 inches
Diameter. distasnce from center to edge is radius length around is circumfrance
26.5/pi = just under 8.5 inches
