If the radii of the circular ends of a bucket $24\ cm$ high are $15\ cm$ and $5\ cm$ respectively, then the surface area of the bucket is $545\pi\text{cm}^2.$
|
if the radii of the circular ends of the frustum of a cone are $R$ and $r$ respectively and its height is $h,$ surface area is:
$\pi\big\{\text{R}^2+\text{r}^2+\text{l}(\text{R}-\text{r})\big\}$
where $\text{l}^2=\text{h}^2+(\text{R}+\text{r})^2.$
