Respuesta:
3) 2√13 cm
4) 65πcm²
Explicación paso a paso:
3)
V = 48πcm³
h = 4cm
g = ?
primero calculamos el radio
48πcm³ = (π.r².4cm)/3
3.48πcm³/4πcm = r²
36cm² = r²
√36cm² = r
6cm = r
ahora calculamos la generatriz
[tex]g=\sqrt{(6cm)^{2}+(4cm)^{2}}[/tex]
[tex]g=\sqrt{36cm^{2}+16cm^{2}}[/tex]
[tex]g = \sqrt{52cm^{2}}[/tex]
[tex]g=2\sqrt{13}cm[/tex]
4)
radio 5cm
altura 12cm
[tex]g=\sqrt{(5cm)^{2}+(12cm)^{2}}[/tex]
[tex]g=\sqrt{25cm^{2}+144cm^{2}}[/tex]
[tex]g=\sqrt{169cm^{2}}[/tex]
g = 13cm
AL = π.5cm.13cm
AL = 65πcm²
