Question

Find the volume of a cylinder whose height and radius of base are 20cm and 28cm respectively.

Answer 1

Answer:

answer is

35,200 cm cube

$35000 {}^{3}$

Answer 2

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

$\green{\therefore{\text{Volume\:of\:cylinder=35200\:cm}^{3}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 20\: cm} \\ \\ : \implies \text{Height(h) = 28 \: cm} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Volume \: of \: cylinder = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{Volume\: of \: cylinder} =\pi r^{2}h \\ \\ : \implies \text{Volume\: of \: cylinder} = \frac{ 22}{7} \times {20}^{2}\times 28\\ \\ : \implies \text{Volume\: of \: cylinder} =22\times 400\times 4\\ \\ \green{ : \implies \text{Volume\: of \: cylinder} =35200 \: {cm}^{3}}\\\\ \purple{\text{Some\:formula\:related\:to\:this\:topic}}\\ \pink{\circ\:\text{C.S.A\:of\:cylinder}=2\pi rh}\\\\ \pink{\circ\: \text{T.S.A\:of\:cylinder}=2\pi r(h+r)}$
