Question

the volume of a cylinder is 660 cm find its height if its radius is 5 cm

Answer 1

volume of cylinder is 660 cm
radius of cylinder is 5 cm
660 = 22/7 ×5×5×h
660×7/22×5×5=h
8.4=h
height h is 8.4 cm

Answer 2

volume of cylinder
$= \pi {r}^{2} h \\ 660 = \pi {5}^{2} h \\ 660 \div 25 = \pi \: h \\ \\ (660 \div 25\pi) = h = 8.40$
here is cylinder
