Step-by-step explanation:

Diameter=10cm

Radius=Diameter/2=10/2=5cm

Now

[tex]\boxed{\sf Volume\:of\: Sphere=\dfrac{4}{3}\pi r^3} [/tex]

[tex]\begin{gathered}\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{4}{3}\times \dfrac{22}{7}\times 5^3\end{gathered}[/tex]

[tex]\begin{gathered}\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{88}{21}\times 125\end{gathered} [/tex]

[tex]\begin{gathered}\\ \tt{:}\leadsto Volume_{(Sphere)}=\dfrac{11000}{21}\end{gathered} [/tex]

[tex]\begin{gathered}\\ \tt{:}\leadsto Volume_{(Sphere)}=523.8\end{gathered} [/tex]

[tex]\begin{gathered}\\ \tt{:}\leadsto Volume_{(Sphere)}=524units^3(Approx)\end{gathered} [/tex]

Volume of the sphere is 524 [tex]cm^{3}[/tex]

What is Volume?

"Volume is the total amount of space occupied by any three dimensional object."

What is sphere?

" A sphere is three dimensional shape which is equidistant from its center."

Formula used to calculate Volume of a sphere

Volume of a sphere = [tex]\frac{4}{3} \pi r^{3}[/tex]

According to question,

Diameter = 10cm

Radius = [tex]\frac{Diameter}{2}[/tex]

           = [tex]\frac{10}{2}[/tex]

           = 5cm

Volume of a sphere = [tex]\frac{4}{3}[/tex] ×[tex]\pi[/tex]×[tex]5^{3}[/tex]

                                 = [tex]\frac{4}{3}[/tex] ×[tex]\frac{22}{7}[/tex] × [tex]5[/tex] × [tex]5[/tex] × [tex]5[/tex]

                                 = 523.8

                                 = 524 [tex]cm^{3}[/tex] (round to the nearest tenth)

Hence Volume of a sphere is 524 [tex]cm^{3}[/tex].
