Find the simplified form of the expression. Give your answer in scientific notation. (8 x 10^4)(9 10^-8)
a.7.2×10^-5
b.7.2×10^-3
c.72×10^-4
d.7.2×10^-31​

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
