When graphing the function (x)= x²-81
x2 - 11x+18
on your graphing calculator, what is the most appropriate viewing window
for determining the domain and range of the function?

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

step-by-step explanation:

1/4 is the answer if i recall correctly.

the equation simplified is 7/8. but the lcd is 8.
