Answer:
Total surface area of a hemisphere: A = 3 * π * r² , Surface to volume ratio of a hemisphere: A / V = 9 / (2 * r) .
After distributing you get this equation. 2r+4 =2r+4 since it's the same expression on both sides the answer would be r=All real numbers because no matter whatever real number u put for r it will come out the same on both sides
I know this is late but the greatest common factor between the two is 2a.
