Radius: 8cm

\sf \: volume \: of \: sphere =  \frac{4}{3} \pi  r ^{3}

  • <u>π</u><u> </u><u>=</u><u> </u><u>3</u><u>.</u><u>1</u><u>4</u>
  • <u>Radius</u><u> </u><u>(</u><u>r</u><u>)</u><u> </u><u>=</u><u> </u><u>8</u><u> </u><u>cm</u>

<u>\sf \:  =  \frac{4}{3}  \times 3.14 \times 8 ^{3}</u>

<u>=  \sf \:  \frac{ \cancel4}{3}  \times  \frac{157} { \cancel5 \cancel0}  \times 8 ^{3}</u>

<u>\sf =  \frac{2}{3}  \times  \frac{157}{25}  \times 8 ^{3}</u>

<u>\sf =  \frac{314 \times 8 ^{3} }{75}</u>

<u>=  \sf  \frac{314 \times 512}{75}</u>

<u>=  \sf  \frac{160768}{75}</u>

<u>\sf = 2143.573 \: cm^{3}</u>

The volume of a sphere whose radius is 8cm is; 2138.2cm³

<h3>Volume of a sphere</h3>

The volume of a sphere is given as;

  • V = (4/3)πr³

Therefore, for the given sphere;

  • V = (4/3) × 3.14 × (8)³

  • V = 1.33 × 3.14 × 512

  • V = 2138.2cm³
