Step-by-step explanation:

  1. a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
  2. perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87

Find the area of the shaded region. Express your answer in terms of π.
Bogdan [553]

Answer:

335.115

Step-by-step explanation:

First you find the area of the circles to do that you do pi times radius squared

For the top square do 3.14(pi)time 3²=28.26

For the middle square do 3.14 times 4.5²=63.585

For the bottom square do 3.14 times 6²=113.04

Now find the area of the entire thing do 18×12+9+6+3=18×30=540

Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115

So the shaded region is 335.115

Hope this helps and have a great day!
