Mrs.penn has a circular tablecloth with a circumference of 29 feet. Which expression could be used ro find the radius of the tablecloth?

f. 29 - 2 pie
g. 29/2 pie
h. 29/pie
j 29 + 2pie

• math -

The formula for the circumference of a circle is C=2(pi)r. If we divide both sides by 2(pi) we have:

C/2(pi)=r

Substituting 29 for C we have:

29/2(pi)=r

and therefore the correct answer would be "g."
