Question

The volume of a cylinder is 252π cm³ and height 7cm.find its radius.​

Answer 1

Step-by-step explanation:

$volume \: of \: a \: cylinder = \pi {r}^{2} h \: \: cubic \: unit$

ATP,

$\pi {r}^{2} h = 252\pi$

${r}^{2} \times 7 = 252$

${r}^{2} = \frac{252}{7}$

${r}^{2} = 36$

$r = \sqrt{36}$

$r = 6$

Answer :- The radius of a cylinder is 6 cm.
