Question

determine a medida da geratriz de um cone circular que apresenta uma área total de 7536 cm2 E raio da base medindo 30 cm
​

Answer 1

$\large\boxed{\begin{array}{l}\sf A= \pi\cdot r(r+g)\\\sf 7536=3,14\cdot30(30+g)\\\sf94,4\cdot(30+g)=7536\\\sf 30+g=\dfrac{7536}{94,4}\\\sf 30+g=79,83\\\sf g=79,83-30\\\sf g=49,83~cm\end{array}}\\\boxed{\begin{array}{l}\displaystyle\sf\ell ife=\int_{birth}^{death}\dfrac{happiness}{time}d_{time}\end{array}}$
