Calcula el radio de un cilindro que tiene 8 cm de altura y un volumen de 122 cm cúbicos

kondaur [170]

Answer:

$\huge{ \boxed{ \sf{2.20 \: cm}}}$

Step-by-step explanation:

$\star{ \sf{ \: altura \: de \: un \: cilindro\: = \: 8 \: cm}}$

$\star{ \sf{ \: volumen \: de \: un \: cilindro = 122 \: cm \: cúbicos}} \:$

$\star { \sf{ \: encontrar :radio \: de \: un \: cilindro }}$

$\boxed{ \sf{ \: Volume \: of \: a \: cylinder \: = \: {\pi \: radius}^{2} \: height}}$

$\mapsto{ \sf{122 \: = \: ( \frac{22}{7} )r \: ^{2} \: \times \: 8}}$

$\mapsto{ \sf{122 = 25.14 \: {r}^{2} }}$

$\mapsto{ \sf{25.14 \: {r}^{2} = 122 }}$

$\mapsto{ \sf{ \frac{25.14 \: {r}^{2} }{25.14} = \frac{122}{25.14}}}$

$\mapsto{ \sf{ {r}^{2} = 4.85 \: cm}}$

$\mapsto{ \sf{r = 2.20 \: cm}}$

radio de un cilindro = 2.20 cm
