Question

The volume of a cylinder is 448πcm3 and height is 7cm .what is it s radius?

Answer 1

$hey \: there \: your \: answer \\ \\ \\ volume \: of \: cylinder = \pi {r}^{2} h \\ so \\ \: \: \: \: \frac{22}{7} \times {r}^{2} \times 7 = 448 \\ \: \: \: \: {r}^{2} = \frac{448 \times 7}{22 \times 7} \\ \: \: \: \: r = \sqrt{ \frac{448}{22} } \\ \: \: \: \: r = 4.51cm \\ \\ \\ please \: mark \: me \: brainlist$
