Question

A cylinder whose radius 3.5cm and height 5cm. Find their volume

Answer 1

Answer:

Step-by-step explanation:

V = pie r sq h

27.5 cm cube

Answer 2

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

$\green{\therefore{\text{Volume\:of\:cylinder=192.5\:cm}^{3}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 3.5\: cm} \\ \\ : \implies \text{Height(h) = 5\: cm} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Volume \: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{Volume\: of \: cylinder} =\pi{r}^{2}h \\ \\ : \implies \text{Volume\: of \: cylinder} = \frac{22}{7} \times {3.5}^{2}\times 5\\ \\ : \implies \text{Volume\: of \: cylinder} =22 \times 1.75\times 5\\ \\ \green{ : \implies \text{Volume\: of \: cylinder} =192.5\: {cm}^{3}}\\\\\purple{\text{Some\:formula\:related\:to\:this\:topic}}\\ \pink{\circ\:\text{C.S.A\:of\:cylinder}=2\pi rh}\\\\ \pink{\circ\: \text{T.S.A\:of\:cylinder}=2\pi r(h+r)}$
