Area of circle =π *r^2
so π*r^2 = π(16x^2 + 24x + 9)
r^2 = 16x^2 + 24x + 9
= (4x +3)(4x+3)
= (4x +3)^2
Take square roots of both sides
r = 4x +3

C is the correct answer 3.785*2.5=9.4625 then multiply by 1000 and you get 9,462.5
I believe it’s the second option because there are two 3’s with different outputs
