A sphere has a diameter of 4 x 10^-3 mm. What is the approximate volume of the sphere? Use 3.14 for pi.
kolezko [41]

Answer:

3.349 \times {10}^{ - 10} \:  {mm}^{3}

Step-by-step explanation:

d = 4 \times  {10}^{ - 3}  \: mm \\ r = 2 \times  {10}^{ - 3}  \: mm \\ V_{sphere}  =  \frac{4}{3} \pi {r}^{3}   \\ = \frac{4}{3}  \times 3.14 \times {(2 \times  {10}^{ - 3} )}^{3} \\  = \frac{4}{3}  \times 3.14 \times 8\times  {10}^{ - 9}  \\ = \frac{100.48}{3}  \times   {10}^{ - 9}  \\  = 33.4933333\times   {10}^{ - 9}  \\  = 33.49 \times {10}^{ - 9} \\  = 3.349 \times {10}^{ - 10} \:  {mm}^{3}
