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

Nikitich [7]

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

Anyone know the correct answer to this?

Svetllana [295]

Answer:

It should be y=4x-7

Step-by-step explanation:

M is the slope meaning Δx over Δy or rise over run

So if you look at (2,2) and count up to (3,6) the rise is 4 and the run is 1 meaning the slope is 4.

B is the y- intercept so then it would just be -7.
