The time spent (in minutes) in reading newspaper for an adult per day can be approximated by a normal distribution with \mu μ =15 minutes and \sigma σ =3 minutes. if 200 adults are randomly selected, approximately how many of them will spend in reading newspaper per day between 12 minutes and 19.5 minutes

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
