Answer:

111,6cm²

Step-by-step explanation:

S.A = 4 * 3,1 * r²

S.A = 4 * 3,1 * 3²

S.A = 4 * 3,1 * 9

S.A = 36 * 3,1

S.A = 111,6

Since √(3x+1) and √(x-5) is always positive, you can square out both sides.

$\sqrt{3x + 1} > \sqrt{x - 5} \\ {( \sqrt{3x + 1}) }^{2} > {( \sqrt{x - 5} )}^{2} \\ 3x + 1 > x - 5 \\ 2x > - 6 \\ x > - 3$

Since substituting x = -2, -1 , ... , 4 into √(3x+1) and √(x-5) will result into complex solutions,

Therefore,

$x > 4$
