Answer 2

Respuesta:

78.5cm

Explicación paso a paso:

$2p = 2 \pi r$

$r = \frac{d}{2} \\ r = \frac{25}{2} = 12.5cm$

$2p = 2(3.14)(12.5) \\ 2p = 2 \times \frac{314}{100} \times \frac{125}{10} \\ 2p = \frac{2 \times 314 \times 125}{100 \times 10} \\ 2p = \frac{628 \times 125}{1000} = \frac{78500}{1000} \\ 2p = 78.5cm$
