multiply all by the least common multiply:

$(\frac{1}{2} ) \times 4 = 2$

$( - \frac{3}{4} ) \times 4 = - 3$

$( \frac{1}{4} ) \times 4 = 1$
$+ 1z = - 3$
$z = \frac{ - 3}{1}$
$z = - 3$

Vsevolod [243]

The formula of a volume of sphere:

$V=\dfrac{4}{3}\pi R^3$

R - radius

We have R = 10. Substitute:

$V=\dfrac{4}{3}\pi(10^3)=\dfrac{4}{3}\pi(1,000)=\boxed{\dfrac{4,000\pi}{3}}$
