Can somebody please help me I am really stuck
to work out the circumference you have to multiple pi by the diameter . since pi is 3 and the diameter is 9. you have to multiply 9 by 3 to work it out.the answer would be 27. hope this helps you
circumference of a circle formula : C = 2 pi rpi = 3r = d/2......= 9/2 = 4.5C = 2 3 4.5 C = 27 cm
