Question

if the volume of a cylinder is 770 cm cube and its diameter is 14 centimetre find the height of the cylinder​

Answer 1

Explicación paso a paso:

1 - the cylinder volume formula is:

$volume \: = \pi \times {r}^{2} \times h \\ volume = 770 \: {cm}^{3} \\ diameter = 14 \: cm \\ radius = \frac{14}{2} = 7 \: cm \\ 770 = \pi \times {7}^{2} \times h \\ \frac{770}{\pi \times {7}^{2} } = h \\ \frac{770}{\pi \times 49} = h \\ h = 5,004 \: cm$
