Question

Del cilindro, calcula el área total. Dato: R = 9cm, h = 20cm.

Answer 1

Respuesta:

AT = 1160$\pi$

AT = 3644.25

Explicación paso a paso:

AL = $2\pi rh$

AL = 2$\pi$(9)(20)

AL = 360$\pi$

AB = $\pi r^{2}$

AB = $\pi 20^{2}$

AB = 400$\pi$

AT = 360$\pi$ + 2 (400$\pi$)

AT = 1160$\pi$

AT = 3644.25
