Sorry for late my is slow

Hope it will help u

Answer 2

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

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

$\green{\therefore{\text{T.S.A\:of\:cylinder=209\:m}^{2}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 3.5\: m} \\ \\ : \implies \text{Height(h) = 6 \: m} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{C.S.A \: of \: cylinder = ? }\\ \\ : \implies \text{T.S.A\: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{C.S.A\: of \: cylinder} =2\pi rh \\ \\ : \implies \text{C.S.A\: of \: cylinder} =2 \times \frac{ 22}{7} \times 3.5\times 6 \\ \\ : \implies \text{C.S.A\: of \: cylinder} =2 \times 22 \times 3 \\ \\ \green{ : \implies \text{C.S.A\: of \: cylinder} =132 \: {m}^{2}} \\ \\ \bold{As \: we \: know \: that} \\ : \implies \text{T.S.A\: of \: cylinder} =2\pi r(h + r) \\ \\ : \implies \text{T.S.A\: of \: cylinder} =2 \times \frac{22}{7} \times 3.5(6 + 3.5) \\ \\ : \implies \text{T.S.A\: of \: cylinder} =2 \times 22 \times 4.75 \\ \\ \green{ : \implies \text{T.S.A\: of \: cylinder} =209 \: {m}^{2} }$
