Cinthya,
El cálculo del volumen es directo usando la fórmula
V(esfera) = [tex] \frac{4}{3} \pi. r^{3} [/tex]
Del enunciado:
V = [tex] \frac{4}{3}.\pi.[2,5.(10^{-3)}]^{3} [/tex]
= [tex] \frac{4}{3}.\pi.(2,5)^{3}.(10^{-3}) ^{3}[/tex]
= [tex] \frac{4}{3}.\pi.(15,625).(10^{-9}) [/tex]
Efectuando:
V = [tex] 2,083.\pi.10 ^{-10} [/tex] [tex] u^{3} [/tex]
