Pregunta 1
[tex]L = \frac{\pi}{4} \times 20 \\ L= 5\pi[/tex]
Pregunta 2
[tex]L = \frac{2\pi}{5} \times 30 \\ L = 12\pi[/tex]
Pregunta 3
[tex]S = \frac{ \frac{\pi}{6} \times {12}^{2} }{2} \\ S = \frac{ \frac{\pi}{6} \times 144}{2} \\ S = \frac{144\pi}{12} \\ S = 12\pi[/tex]
Pregunta 4
[tex]S = \frac{8\pi \times 6}{2} \\ S = \frac{48\pi}{2} \\ S = 24\pi [/tex]
Pregunta 5
[tex]S = \frac{ \frac{\pi}{4} \times {6}^{2} }{2} \\ S = \frac{ \frac{\pi}{4} \times 36}{2} \\ S = \frac{36\pi}{8} \\ S = \frac{9\pi}{2} \: \: o \: \: 4.5\pi[/tex]
