Maria encheu um copo cilíndrico, cujo raio da base mede 3 cm, e a altura mede 12 cm, com água até \( { \large 2 \over 3} \) de sua capacidade. Depois, sem que houvesse desperdício, transferiu toda a água para outro copo, também cilíndrico e inicialmente vazio, de 4 cm de raio da base.
Qual foi, em cm, a altura atingida pela água no segundo copo?

O número de telefones fixos no Brasil continua em crescimento. De acordo com dados que a Anatel divulgará nos próximos dias, de 2010 para 2011, esse total passou de 42,1 milhões para 43 milhões de linhas.
Revista Veja. São Paulo: Abril. 6 jun. 2012, p. 63. Adaptado.
Supondo que o aumento observado de 2010 para 2011 seja linear e que assim se mantenha nos próximos anos, quantos milhões de telefones fixos haverá, no Brasil, em 2013?

Committee decides to lower the use of thermoelectric power generation
GTCIT Magazine
The Monitoring Committee of the Electric Sector
(CMSE) decided on Monday (May 30, 2012), to
diminish the thermoelectric power generation in Brazil
as of next week. According to the Ministry of Mines
and Energy, Márcio Zimmermann, the thermoelectric
generation, which currently averages 4.000 megawatts
(MW), should now be reduced to 2.500 MW.
These plants are used in Brazil mainly to prevent
a power outage in the country in times of drought,
when the reservoirs of the dams are low. But the
ministry assured that the reservoir of the hydroelectric
plants are satisfactory, and that there will be no need
to resort to the thermoelectric resources.
According to the Minister Zimmermann, the
Southeast has an average of 90% of its reservoirs full,
which is an excellent level for this time of year. Even
the Northeast, whose reservoir levels are a little lower,
do not compromise system security.
“The system is operating perfectly within the
current conditions, which safely allows us to reduce
the generation of thermoelectric energy. This will give
us an economic surplus that can be used towards
system maintenance and in the implementation of
new quality programs for the energy sector”, he said.
He also explained that: “of course, this does not
mean that the committee will not be flexible as to
this decision in case the current conditions take an
unexpected turn.” They will be following the reduction
of the projection for the coming months and, if
necessary, the plans will be changed according to
the demands vis-a-vis the resources.
