The curved surface area and the volume of a cylinder are 264 cm$$^2$$ and 924 cm$$^3$$, respectively. What is the ratio of its radius to height ?(Take $$\pi = \frac{22}{7}$$)
We have :
$$2\pi\ rh\ =264$$
$$\pi r^2h\ =924$$
Dividing we get r/2 = 924/264
r = 7Â
Substituting we get h =6Â
Now r:h = 7:6
