Answer 1

Respuesta:

Pregunta 1

$L = \frac{\pi}{4} \times 20 \\ L= 5\pi$

Pregunta 2

$L = \frac{2\pi}{5} \times 30 \\ L = 12\pi$

Pregunta 3

$S = \frac{ \frac{\pi}{6} \times {12}^{2} }{2} \\ S = \frac{ \frac{\pi}{6} \times 144}{2} \\ S = \frac{144\pi}{12} \\ S = 12\pi$

Pregunta 4

$S = \frac{8\pi \times 6}{2} \\ S = \frac{48\pi}{2} \\ S = 24\pi$

Pregunta 5

$S = \frac{ \frac{\pi}{4} \times {6}^{2} }{2} \\ S = \frac{ \frac{\pi}{4} \times 36}{2} \\ S = \frac{36\pi}{8} \\ S = \frac{9\pi}{2} \: \: o \: \: 4.5\pi$
