Question

Find the volume of the cylinder whose radius is 4cm and height is 82cm.

Answer 1

heya your answer is here....
radius of cylinder is given as 4 cm
and height is 82 cm.

we know that,
volume of cylinder = πr²h
V= 22/7*4²*82
V= 4123.43cm³

Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{Volume\:of\:cylinder=4119.68\:cm}^{3}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 4\: cm} \\ \\ : \implies \text{Height(h) = 82\: cm} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Volume \: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{Volume\: of \: cylinder} =\pi{r}^{2}h \\ \\ : \implies \text{Volume\: of \: cylinder} = \frac{22}{7} \times {4}^{2}\times 82\\ \\ : \implies \text{Volume\: of \: cylinder} =3.14\times 16\times 82 \\ \\ \green{ : \implies \text{Volume\: of \: cylinder} =4119.68\: {cm}^{3}}\\\\\purple{\text{Some\:formula\:related\:to\:this\:topic}}\\ \pink{\circ\:\text{C.S.A\:of\:cylinder}=2\pi rh}\\\\ \pink{\circ\: \text{T.S.A\:of\:cylinder}=2\pi r(h+r)}$
