Пошаговое объяснение:

S поверхности=4πR^{2}

V= 4/3πR^{3}

З  площади поверхности вычислим радиус

144π/4π=36^{2}

значит

R= 6 см

V= 4/3*36*6=288\pi ^{3}

Ответ:   288/π²=29.1.

Пошаговое объяснение:

Площадь сферы S=4πR²;  144=4πR²;

πR²=36;

R²=36/π;

R=√36/π;

R=6/π.

--------------

V=4/3πR³=4/3π(6/π)³=4/3*π*216/π³=288/π²=29.1.
