Question

the curved surface area of a cylinder is 44 CM square and its radius is 5 centimetre find its heightn​

Answer 1

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

$\green{\tt{\therefore{Height\:of\:cylinder=1.4\:cm}}}$

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

$\green{\underline \bold{Given :}} \\ \tt: \implies C.S.A\: of \: cylinder = 44 \: cm^{2} \\ \\ \tt: \implies Radius \: of \: cylinder = 5 \: cm \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Height \: of \: cylinder =$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies C.S.A\: of \: cylinder = 44 \\ \\ \tt: \implies 2\pi rh = 44 \\ \\ \tt: \implies 2 \times \frac{22}{7} \times 5 \times h = 44 \\ \\ \tt: \implies h = \frac{44 \times 7}{22 \times 2 \times 5} \\ \\ \tt: \implies h = \frac{7}{5} \\ \\ \green{\tt: \implies h = 1.4 \: cm} \\ \\ \green{\tt \therefore Height \: of \: cylinder \: is \: 1.4 \: cm}$

Answer 2

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

$\green{\tt{\therefore{Height\:of\:cylinder=1.4\:cm}}}$

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

$\green{\underline \bold{Given :}}$

$\tt: \implies C.S.A\: of \: cylinder = 44 \: cm^{2}$

$\tt: \implies Radius \: of \: cylinder = 5 \: cm$

$\red{\underline \bold{To \: Find :}}$

$\tt: \implies Height \: of \: cylinder =$

• Given Question

$\bold{As \: we \: know \: that}$

$\tt: \implies C.S.A\: of \: cylinder = 44$

$\tt: \implies 2\pi rh = 44$

$\tt: \implies 2 \times \frac{22}{7} \times 5 \times h = 44$

$\tt: \implies h = \frac{44 \times 7}{22 \times 2 \times 5}$

$\tt: \implies h = \frac{7}{5}$

$\green{\tt: \implies h = 1.4 \: cm}$

$\green{\tt \therefore Height \: of \: cylinder \: is \: 1.4 \: cm}$
