Work it out the circumfrance of a circle is pie x the diameter!
If you take pi as 22/7 the the circumference is 242 cm.

Work it out the circumfrance of a circle is pie x the diameter!
If you take pi as 22/7 the the circumference is 242 cm.
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
7.5Radius of circle: 15/2 = 7.5 cm
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm

To find the circumfrance of a circle, you need to multiply 2 times pi, times the circle's radius. If you don't know what that is, you multiply two times pi, and pi equals 3.14, and then multiply that by the radius, which is the measurement of half the circl'e diameter. the diameter is the distance from one side of the circle, to the exact opposite. you measure this with a ruler. HALF the measurement of the diameter is the radius. Example---the diameter of a circle is 20 cm. half the diameter is 10 cm, which is the radius. Multiply 2 times pi[which equals 3.14], times the radius. Good luck!
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.

A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
