circumference formula is pi(diameter) diameter is 2(radius) radis=4; diameter=2(4)=8 pi(8)=circumference of the circle...this is the EXACT answer plug it into a calculator and you will get 25.1327412287 your welcome ;)
If you're talking about the radius being 24 cm, then the the circumference is exactly 48 PI. If the diameter is 24 cm, then the circumference is 24 PI
circumference = 2πr = 2π x 6 = 12π units
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.
pi times the diammeter 3.14159 x diameterDan's answer:circumference= pi X diameter.2pi X Radius=Pi X Radius (x2)
