Question

calcular el área total de un cilindro , cuyo radio de la base es de 4 cm y altura 6cm *

Answer 1

Explicación paso a paso:

Area base

$b = \pi {r}^{2} \\ b = 3.14 \times 4 \\ b = 12.56$

Area lateral

$l = 2\pi \: rh \\ l = 2(3.14)(4)(6) \\ l = 6.28(24) \\ l = 150.72$

Area total

$area \: total = ab + al \\ = 12.56 + 150.72 \\ = 163.28$
