A chemical engineer is trying to increase the amount of the useful product in a reaction. She performs the reaction with her new equipment 10 times
and gets the following amounts of the useful product: What proportion of the reactions were above the 48 grams threshold?

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
