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
j 29 + 2pie
The formula for the circumference of a circle is C=2(pi)r. If we divide both sides by 2(pi) we have:
Substituting 29 for C we have:
and therefore the correct answer would be "g."
