Question

Hallar el volumen de una esfera de radio igual a 2cm y 7cm

Answer 1

$Hola!\\\\El~volumen~de~una~esfera~es:~\boxed{V=\frac{4}{3} \pi.r\³}\\\\El~volumen~cuando~el~radio~tiene~\boxed{r=2cm}\\\\\bigstar~V=\frac{4}{3}.\pi.(2cm)\³~~valor~del~\boxed{\pi=3,14}\\\\~~~~~V=\frac{[4.(3,14).(8cm)]}{3}\\\\~~~~~\boxed{\boxed{V=33,49cm\³}}$

$=====================================\\\bigstar~Cuando~el~radio~\boxed{r=7cm}\\\\~~~~~V=\frac{4}{3}.\pi. (7cm)\³\\\\~~~~~V=\frac{[4(3,14)(343cm\³)]}{3}\\\\~~~~~\boxed{\boxed{V=1436,0,27cm\³}}$

Answer 2

Respuesta:

Sabemos que el volumen de una esfera es:

4/3×pi×r^3 entonces sustituimos valores:

V=4/3×pi×(7)^3

V=4/3×pi×343

V=1372/3×pi cm^3~~1436.75cm^3
