Question

find the volume, curved surface area of each sides of the cylinder s whose dimensions are: radius- 14 dm, height - 15m​

Answer 1

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

$\green{\therefore{\text{Volume\:of\:cylinder=92.4\:m}^{3}}}$

$\green{\therefore{\text{C.S.A\:of\:cylinder=132\:m}^{2}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 14 \: dm} \\ \\ : \implies \text{Height(h) = 15 \: m} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Volume \: of \: cylinder = ? }\\ \\ : \implies \text{C.S.A \: of \: cylinder = ?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ : \implies \text{Volume \: of \: cylinder} = \pi {r}^{2} h \\ \\ : \implies \text{Volume \: of \: cylinder} = \frac{22}{7} \times {1.4}^{2} \times 15\\ \\ : \implies \text{Volume \: of \: cylinder} =22 \times 0.28 \times 15 \\ \\ \green{ : \implies \text{Volume \: of \: cylinder} =92.4 \: {m}^{3} } \\ \\ \bold{As \: we \: know \: that} \\ : \implies \text{C.S.A\: of \: cylinder} =2\pi rh \\ \\ : \implies \text{C.S.A\: of \: cylinder} =2 \times \frac{ 22}{7} \times 1.4 \times 15 \\ \\ : \implies \text{C.S.A\: of \: cylinder} =2 \times 22 \times 3 \\ \\ \green{ : \implies \text{C.S.A\: of \: cylinder} =132 \: {m}^{2}}$
