Can someone please help me with this

Alright!

To solve, all we need to do is subtract the area of the inner circle from the arear of the outer circle.

But first, we need to find the area of both

Key equation: πr²

π = 3.14

Inner cirle area = π13²

π13² = 530.66

Outer cirle area = π21²

I got 21 by adding 8 and 13: both added together makes the radius of the larger circle

π21² = 1,385.74

Now let's subtract.

1,385.74 - 530.66 = 855.08

The area of the blue is = 855.08 yards²

The answer is C. 93.53

what grade level is this? need to know so i can look in my old textbooks!

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|
