Answer 1

Answer:

Find:

Ratio of curved surface area of Cylinder and Surface Area of Sphere

Solution:

we, know that

\boxed{\sf Curved \: surface \: area \: of \: cylinder = 2 \pi rh}

Curvedsurfaceareaofcylinder=2πrh

And,

\boxed{\sf surface \: area \: of \: sphere = 4 \pi {r}^{2} }

surfaceareaofsphere=4πr

2

So,

\begin{gathered}\heartsuit \sf Ratio = \dfrac{curved \: surface \: area \: of \: cylinder}{surface \: area \: of \: sphere} \\ \\ \\ \dashrightarrow \sf Ratio = \dfrac{2 \pi rh}{4 \pi {r}^{2} } \\ \\ \\ \dashrightarrow \sf Ratio = \dfrac{rh}{2{r}^{2} }\\ \\ \\ \dashrightarrow \sf Ratio = \dfrac{rh}{2{r}^{2} }\\ \\ \\ \dashrightarrow \sf Ratio = \dfrac{rh}{2r \times r}\\ \\ \\ \dashrightarrow \sf Ratio = \dfrac{h}{2r}\end{gathered}
