Question

Find T.S.A of cylinder whose radius 7 cm and height is 10 cm.​

Answer 1

Answer:

TSA of cylinder =2πr(h+r)

So 2×22/7×7(10+7)

44× 17

748 cm ^ 2 ans.............

$\green{\tt{\therefore{T.S.A\:of\:cylinder=748\:cm^{2}}}}$

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

$\green{\underline \bold{Given :}} \\ \tt:\implies Radius\: of \: cylinder = 7 \: {cm} \\ \\ \tt: \implies Height \: of \: cylinder = 10 \: cm \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies T.S.A \: of \: cylinder = ?$

• According to given question :

$\bold{As \: we \: know \:that} \\ \tt: \implies T.S.A \: of \: cylinder = 2 \pi r(h + r) \\ \\ \tt: \implies T.S.A \: of \: cylinder =2 \times \frac{22}{7}\times 7(10 + 7) \\ \\ \tt: \implies T.S.A\: of \: cylinder =2 \times 22\times 17 \\ \\ \green{\tt: \implies T.S.A \: of \: cylinder =748\: {cm}^{2} }$

$\purple{\bold{Some \: related \: formula}} \\ \pink{\tt\circ \: C.S.A\: of \: cylinder = 2\pi rh} \\ \\ \pink{\tt\circ \: Volume \: of \: cylinder = \pi{r}^{2}h }$
