lap top- 398 ÷ 809 = 0.49%

printer- 64 ÷ 809 = 0.08%

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
