Ms Happy has decided to start wearing a face mask, because it is now required of her to do so. The mask she has started wearing is very colorful and measures 9 inches by 5 inches. She is extremely bored, so she wonders what percent of her face is uncovered. Given that her face is roughly the shape of a circle (she put on a few pounds over Spring Break and Easter) with a circumference of 30 inches, find the percent of her face that is uncovered. Use 3.14 for pi and round your answer to 2 decimal places and don't forget the percent symbol.
