Question

Un cilindru circular drept are volumul egal cu 588 pi m cubi,iar raza bazei R=7 m.Calculati:
a) h b) Al c) At E URGENT IMI TREBUIE MAINE,MULTUMESC! :*

Answer 1

a) V= $\pi R^{2} h$
$588 \pi =49 \pi h$
$h= \frac{588 \pi }{49 \pi } =12$ m
b) Al= $2 \pi RG$
$Al=2*7*12 \pi =168 \pi cm^{2}$
c) At = $\pi R(R+G) = 7 \pi * 84 = 588 \pi cm^{2}$
