Diameter. distasnce from center to edge is radius length around is circumfrance
To find the circumference of a circle, you have to multiply Pi and the Diameter. This means that to work out the answer you multiply Pi by 1.25. This equals 3.92699081, which rounded equals 3.93 (2dp) - the circumference of a circle with a 1.25 diameter.
Divide the circumference by pi.
The radius is half of the diameter of a circle.
What measurement of the circle is equal to 49 inches? is it the radius?, the area?, the circumference? Without further information this question can not be answered satisfactorily.
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
If you take pi as 22/7 the the circumference is 242 cm.
circumfrance= pi x diameterc= pi x 6c= 18.85
If that's the diameter, multiply the diameter by pi (which is about 3.1416). If it's the radius, multiply it by (2 x pi).
