$C=2*\pi*r$

hi

@RebeccaPink6398 OK - the answer you gave was pi * r the formula for the circumference is pi * D ( the diameter) bur the diameter = 2*radius so the circumference = pi * D OR 2*pi *r so you were nearly right - use 2*pi * r to get the right answer

@MrNood so B?

5. MrNood

you haven't posted the options but if B is equal to 2*3.14*48 then it is the answer

if B is equal to 2*3.14*48 then it is the answer
