A sphere has a radius of 3x+2. Which polynomial in standard form best describes the total surface area of the sphere?

Question

anonymous · Answer

Note: Use the formula S = 4r2 for the surface area of a sphere.
don't pay attention to this if you don't want, I'm just thinking

16$$\pi$$ x^2+16$$\pi$$
16 pi x^2+48pi x+16 pi
36pix^2+48 pi x+16 pi
36 pi x^2+24 pi x+ 16 pi

note: 4(3x+2)2

can u put the work up please

anonymous · Answer

hold on a sec

anonymous · Answer

radius = 3x+2
diameter = (3x+2)*2
area = (Pi(3.14)*radius^2) = (3.14*(3x+2)^2) | PI(3x+2)2
