1a)      A = 4πpw
      /4πw = /4πw
  A / 4πw = p

1b) A = 4πpw
     22 = 4πp(2)
       p = 11/4π (≈0.87)

2a)        P = 2πr + 2x
      P - 2x = 2πr
        /2π      /2π
 P-2x / 2π = r

2b)    P = 2πr + 2x
      440 = 2πr + 2(110)
          r = 110/π (≈35.014)

Which statement describes a number with the smallest absolute value?
Snezhnost [94]
I believe C. The temperature is -23 degrees.

This is because, a negative (absolute value) becomes positive

Which would lead for |-23| to end up being |23|

Anytime a negative absolute value is placed, it becomes a positive and a positive stays positive.

So the smallest would be C then B later D and at last A
