Trigonometria – circunferencias,arcos de circuferencia
Um casal estava no parque e resolveu passear na roda-gigante. Quando percorreram um arco de 32 pi dividido por 3 metros, a roda gigante,inesperadamente, parou, e o telefone celular da mulher caiu verticalmente, atingindo o chão.
sabendo q o raio da circuferancia da roda gigante e de 8 metros e que a distancia entre essa circuferencia e o chão é de 2 metros,determine a altura aproximada da queda do telefone.
