Volume

[tex]___________________________________[/tex]

First, let us find the radius

[tex]\large\tt\color{viole}R = \frac{diameter}{2} [/tex]

[tex]\large\tt\color{vilet}R = \frac{10 \: cm}{2} [/tex]

[tex]\large\tt\color{violt}R = 5 \: cm[/tex]

Second, find the Volume

[tex]\large\tt\color{vioet}V = \frac{4}{3} \pi r {}^{} [/tex]

[tex]\large\tt\color{vilet}V = \frac{4}{3}(3.14)(5 \: cm) {}^{3} [/tex]

[tex]\large\tt\color{vilet}V = \frac{4}{3} (3.14)(125 \: cm {}^{3} )[/tex]

[tex]\large\tt\color{vioet}V = \frac{4}{3} (392.5 \: cm {}^{3} )[/tex]

[tex]\large\tt\color{red}V = 523.33 \: cm {}^{3} [/tex]

  • Therefore, the volume of the sphere is 523.33 cu.cm.
