The wood of a tree has a density of 0.4 gram per cubic centimeter. three 40-centimeter logs have been cut from different sections of the tree trunk

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

it would rotate about 180 degrees.

using pemdas, (order of operations) you'll see the answer is 24.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to

pls mark as brainliest
