Question

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

Answer 1

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

Answer 2

@crazyinlove any given answers?

Answer 3

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

Answer 4

note: 4(3x+2)2

Answer 5

ok im not completely sure but i think its "16 pi x^2+48pi x+16 pi"

Answer 6

can u put the work up please

Answer 7

hold on a sec

Answer 8

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

Answer 9

thank u

Answer 10

np and thats as far as i can go... my mind can't handle it XD
