Y=x+4, 2x+y=13 solve the following system of equation. Please help

alexandr1967 [171]

Well you have to subtract -2 to both sides and it well look like Y= -2+13 and then y=x+4

Answer:

The radius of the sphere is $6\ cm$

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

In this problem we have

$V=288\pi\ cm^{3}$

substitute and solve for r

$288\pi=\frac{4}{3}\pi r^{3}$

simplify

$288*3/4=r^{3}$

$r^{3}=216$

$r=6\ cm$
