CIRCUMFERENCE OF A CIRCLE CAN BE FOUND USING THE FORMULA :

$c = 2\pi \: r \\ \\ or \\ c = \pi \: d$

BUT NOTE d WHICH IS THE DIAMETER IS TWICE THE RADIUS r MEANING IF YOU WERE TO USE THE FORMULA

$c = \pi \: d$

YOU WOULD USE

$d = 2(7.9) \\ d = 15.8 \\ c = (3.14)15.8) \\ c = 49.612 \: \: inches$

NOTE THE TWO FORMULAS RETURNED THE RIGHT CORRECT ANSWER

GOODLUCK!

ALL THESE FORMULAS CAN LEAD YOU TO THE CORRECT ANSWER

$c = 2(3.14)(7.9) \\ c = 49.612 \: inches$
