Question

Calcule o valor do sólido

Answer 1

Resposta:

$a) v = a {}^{3}$

$v = 7.5 {}^{3}$

$v = 421,875 \: cm {}^{3}$

$b) \: v = a \times b \times c$

$v = 20 \times 5 \times 12$

$v = 1200 \: cm {}^{3}$

$c) \: v = \pi \times h \times r {}^{2}$

$v = \pi \times 25 \times 7 {}^{2}$

$v = \pi \times 25 \times 49$

$v = 1225 \: cm {}^{3}$
