The diameter of a sphere is 21.6 cm. What is the sphere's volume? Round to the nearest tenth, if necessary.

Respuesta :

By definition, the volume of a sphere is:
 [tex]V = \frac{4}{3} (\pi) (r ^ 3) [/tex]
 Where,
 r: sphere radio
 Substituting values we have:
 [tex] V = \frac{4}{3}(3.14)(( \frac{21.6}{2} ) ^ 3) [/tex]
 [tex]V = 5273.99424 [/tex] Rounding the result to the nearest tenth:
 [tex]V = 5274.0 cm ^ 3 [/tex] Answer:
 the sphere's volume is:
 [tex]V = 5274.0 cm ^ 3 [/tex]
