Answer:

Step-by-step explanation:

(3w^4-8w^2z^2+4z^4)-(5w^4+7w^2z^2-8z^4)

=3w^4-8w^2z^2+4z^4-5w^4-7w^2z^2+8z^4

=(3-5)w^4+(-8-7)w^2z^2+(4+8)z^4

so she made mistake in step 2.

The volume of a sphere is 5000 pi m 3 what is the surface area

Nikitich [7]

$V = \frac{4}{3}\pi r^3
\\ 5000\pi = \frac{4}{3} \pi r^3
\\ 5000 = \frac{4}{3} r^3
\\ \frac{3}{4} * 5000 = r^3
\\ 3750 = r^3
\\ r = 15.536
\\ SA = 4 \pi r^2
\\ SA = 4\pi (15.536)^2
\\ SA = 3033.11$
