Question

Q. The curved surface area of na right circular cylinder of height 14 cm is 88 cm² . Find the diameter of the base of the cylinder.

Answer 1

Dear Student,

$$\begin{gathered} Heightofcylinder=14cm \\ Radiusofcylinder=r \\ Curvedsurfaceareaofcylinder=88c{m}^2 \\ 2\mathrm{\pi rh}=88 \\ 2\times \frac{22}{7}\times \mathrm{r}\times 14=88 \\ \mathrm{r}=\frac{88\times 7}{2\times 22\times 14} \\ \mathrm{r}=1\mathrm{cm} \\ \mathrm{Diameter}=2\times \mathrm{radius} \\ \mathrm{diameter}=2\mathrm{cm} \end{gathered}$$
