[tex] \sf{a = \sin\left( \frac{\pi}{3} \right) \times \cos\left( \frac{\pi}{3} \right) } \\ \\ \sf{a = \frac{ \sqrt{3} }{2} \times \cos\left( \frac{\pi}{3} \right) } \\ \\ \sf{a = \frac{ \sqrt{3} }{2} \times \frac{1}{2} } \\ \\ \sf{a = \frac{ \sqrt{3} \times 1}{2 \times 2} } \\ \\ \sf{a = \frac{ \sqrt{3} }{2 \times 2} } \\ \\ \boxed{ \sf{a = \frac{ \sqrt{3} }{4} }}[/tex]
Resposta
