The circumference of a circle is 8π cm. What is the circle's area? 32 π cm 2 16 π cm 2 8 π cm 2 64 π cm 2

16

Step-by-step explanation:

we know that the formula for finding area of circle is A=r^2. and circumference of circle can be calculated by c=2r.

first we need find radius from circumference formula and put in area formula to get the desired result.

for radius, r=c/2 =8/2 we get 4. now put in area formula as shown above.

we get , A=*(4)^2 =*4*4 =16

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|
