Question

find total surface area of cylinder whose radius is 2m and hieght is 2m

Answer 1

$total \: surface \: area \: of \: cylinder = 2\pi \: \times r(h + r) \ \\ = \ \ 2 \times 3.14 \times 2 \times (2 + 2) \\ = 2 \times 3.14 \times 2 \times 4 \\ = 50.24 \\ total \: surface \: area \: of \: cylinde \: is \: 50.24 \: sq.m$

Answer 2

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

$\green{\therefore{\text{T.S.A\:of\:cylinder=50.24\:m}^{2}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 2\: m} \\ \\ : \implies \text{Height(h) = 2\: m} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{T.S.A\: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{T.S.A\: of \: cylinder} =2\pi r(h + r) \\ \\ : \implies \text{T.S.A\: of \: cylinder} =2 \times \frac{22}{7} \times 2(2+ 2) \\ \\ : \implies \text{T.S.A\: of \: cylinder} =2 \times 3.14 \times 8 \\ \\ \green{ : \implies \text{T.S.A\: of \: cylinder}=50.24 \: {cm}^{2} }$

$\blue{\text{Some \: related \: formula \: to \: this \: topic}} \\ \pink{\circ \: \text{C.S.A \: of \: cylinder = }2\pi rh} \\ \\ \pink{\circ \: \text{Volume \: of \: cylinder = }\pi {r}^{2} h}$
