The wood of a tree has a density of 0.5 gram per cubic centimeter. Three 50-centimeter logs have been cut from different sections of the tree trunk. The log from the upper section of the trunk has a radius of 20 centimeters.
The log from the middle section of the trunk has a radius of 25 centimeters.
The log from the lower section of the trunk has a radius of 30 centimeters.
Find the mass of each log to the nearest kilogram.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
