The circumference is merely increased by 50%. The formula for a circle (which I assume you know) is 2*pi*r. Work out this value, then multiply it by 1.5. You get the same answer as multiplying 2*pi*(r*1.5). Just fyi (if you didn't know), multiplying something by 1.5 increases it by 50%, multiplying something by 1.12 increases something by 12% etc.
Well you can automatically eliminate, A, because when you multiply one number that's positive and another number that's negative the result is always going to be negative.
However, when you multiply two negatives the result is always positive!
So, the only ones up there that would result in a positive number is B and C
***D. was not posted so I cannot determine that one!
