STEP 1: find radius $ r $

To find radius $ r $ use formula:

$$ V = \dfrac{ 4 \cdot r^3 \cdot \pi }{ 3 }$$

After substituting $V = 7195\, \text{cm}$ we have:

$$ 7195\, \text{cm} = \dfrac{ 4 \cdot r^3 \cdot \pi }{ 3 }$$ $$ 7195\, \text{cm} \cdot 3 = 4 \cdot r^3 \cdot \pi $$ $$ 21585\, \text{cm} = 4 \cdot r^3 \cdot \pi $$ $$ r^3 \cdot \pi = \dfrac{ 21585\, \text{cm} }{ 4 } $$ $$ r^3 \cdot \pi = \frac{ 21585 }{ 4 }\, \text{cm} $$ $$ r = \sqrt[3]{ \frac{ \frac{ 21585 }{ 4 }\, \text{cm} }{\pi} } $$ $$ r \approx 11.9761 $$

STEP 2: find diameter $ d $

To find diameter $ d $ use formula:

$$ d = 2 \cdot r $$

After substituting $r = 11.9761\, \text{cm}^0$ we have:

$$ d = 2 \cdot 11.9761 $$ $$ d \approx 23.9521 $$
