Question

Find the height of a cylinder whose volume is 1.54m3 and diameter of the base is 1.4m??

Answer 1

$d = 1.4m \\ r = \frac{d}{2} \\ = \frac{1.4}{2} \\ = 0.7m \\ volume = 1.54 {m}^{3}$

$Volume \: \: of \: \: cylinder = \pi {r}^{2} h \\ 1.54 = \pi {r}^{2} h \\ h = \frac{1.54 \times 7}{22 \times 0.7 \times 0.7} \\ h = \frac{10.78}{10.87} h = 1m \: \: \: (answer)$
