14. Find the volume of the sphere. Use 3.14 for pi and round to the nearest tenth if necessary.
marissa [1.9K]

Answer:

  • Volume of the sphere is 904.3 mi³

Step-by-step explanation:

Given that radius of the sphere is 6 miles. To find Volume of the sphere we will substitute the Value of radius in the given formula:

\\  \:  \: \dashrightarrow { \underline{ \boxed { \pink{ \pmb{ \mathfrak {Volume_{(Sphere)} = \dfrac{4}{3} \pi r ^3 }}}}}} \\ \\

<em>Substituting</em><em> </em><em>the </em><em>required</em><em> </em><em>values:</em>

\\ \:  \: \dashrightarrow \sf \:  \:  Volume =  \dfrac{4}{3}  \times  3.14  \times  {(6)}^{3} \\ \\

\:  \: \dashrightarrow \sf \:  \:  Volume =  \dfrac{4}{3}  \times 3.14 \times 216 \\ \\

\:  \: \dashrightarrow \sf \:  \:  Volume =  \dfrac{4}{3}  \times 678.24 \\ \\

\:  \: \dashrightarrow \sf \:  \:  Volume =  \dfrac{2712.96}{3}  \\  \\

\:  \: \dashrightarrow \sf \:  \:     {  \underline{ \boxed{ \pink{ \pmb{ \mathfrak{Volume \approx 904.3 \:  {mi}^{3} }}}}}} \\  \\

Hence,

  • <u>Volume of </u><u>the </u><u>sphere is 904.3 mi³</u>
