If two legs of a right triangle are 9 and 11, the hypotenuse is

√202

Step-by-step explanation:

h^2 = p^2 + b^2

or, h^2 = 81 + 121

or h^2 = 202

h =√202

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
