Acircular rug has an area of 32.15 . what is the diameter of the rug, to the nearest tenth of a foot? plz show work and explain.
a. 8 feet
b. 16.1 feet
c. 3.2 feet
d. 6.4 feet

Diameter is twice the radius.  A=πr^2.

First, solve for r:

32.15=πr^2

*Divide both sides by π*

10.2337=r^2

*Take the square root of both sides*

3.199=r

Multiply the radius by 2:

3.199*2=6.398

D. 6.4 feet

Hope this helps!!

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|
