We can solve for the circumference using the following formula:

where r is the radius of the circleSolving the QuestionPart A

We're given:

The radius of the circle is 14 cm

Plug the given information into the formula for circumference:

Therefore, the circumference of the circle is 28π cm.

Part B

Replace π with :

Therefore, the circumference of the circle with is 88 cm.

Let's call  x = profit from the sweatshirt sales  1) a vendor pays to rock band 13% of the total profit from t-shirts and sweatshirts sold at every concert.  2) the profit from t-shirts sales was $ 1,632  3) the vendor paid the rock band $ 726 after the last concert  we then have the following equation:   0.13 * (1632 + x) = 726  clearing x:   (1632 + x) = (726 / 0.13)  x = (726 / 0.13) - 1632 = 3953 $  answer:   the profit from sweatshirt sales was 3953 $
