Question

find the volume of the cylinder whose radius is 0.7cm and height is 8cm

Answer 1

V of cylinder =π r2h
so, radius of the cylinder=0.7
height of the cylinder=8cm
then ,the volume will be=12.32

Answer 2

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

$\green{\therefore{\text{Volume\:of\:cylinder=12.32\:cm}^{3}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 0.7\: cm} \\ \\ : \implies \text{Height(h) = 8 \: cm} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Volume \: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{Volume\: of \: cylinder} =\pi{r}^{2}h \\ \\ : \implies \text{Volume\: of \: cylinder} = \frac{22}{7} \times {0.7}^{2}\times 8\\ \\ : \implies \text{Volume\: of \: cylinder} =22 \times 0.7\times 8 \\ \\ \green{ : \implies \text{Volume\: of \: cylinder} =12.32 \: {cm}^{3}}\\\\\purple{\text{Some\:formula\:related\:to\:this\:topic}}\\ \pink{\circ\:\text{C.S.A\:of\:cylinder}=2\pi rh}\\\\ \pink{\circ\: \text{T.S.A\:of\:cylinder}=2\pi r(h+r)}$
