Not sure what dimensions means but this is what I got out of it , hope it helps !
8 x 5 = 40
40 x 18 = 720
Hope this helps!
I think it is false, because you can have a contradicting statement to a true statement
<span> -k - (-8k) = -k + 8k = 7k</span>
C = pi * d
Plug in what we know:
C = 3.14 * 26
Multiply:
C = 81.64
