ayudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa plz

Answer 1

Explicación paso a paso:

Primero se calcula el radio DO, usando Pitágoras

${c}^{2} = {a}^{2} + {b}^{2} \\ {10}^{2} = {8}^{2} + {b}^{2} \\ 100 = 64 + {b}^{2} \\ 100 - 64 = {b}^{2} \\ {b}^{2} = 36 \\ b = \sqrt{36} \\ b = 36 \: u$

el radio del cilindro es 6 u

su altura 8 u

volumen del cilindro

V=πr²h

$V = \pi \: ( {6})^{2} (8) \\ V = \pi(36)(8) \\ V = 288\pi \: u \\ V = 904.778 \: u$

Área lateral del cilindro de radio=8u y altura=10 u

V=2πrh

$V = 2\pi(8)(10) \\ V = 2\pi(80) \\ V = 160\pi \\ V = 502.654 \: u$
