Question

The height of a cylinder of volume 1100cm³and radius 5cm

Answer 1

$volume \: of \: cylinder \\ = \pi \times (radius) {}^{2} \times (hieght) \\ v = \pi {r}^{2} h \\ < < \ pi = \frac{22}{7} > >$

$1100 = \frac{22}{7} \times 5 {}^{2} \times h \\ h = \frac{1100 \times 7}{22 \times 5 \times 5} = 14 \: cm$
