\n\"AP
\nCSA \/ LSA of cylinder = 2\u03c0rh
\nCSA of cone = \u03c0rl
\nThe lateral surface area of a cylinder is equal to the curved surface area of cone.
\n\u2234 2\u03c0rh = \u03c0rl

Question 5.
\nA self help group wants to manufacture joker’s caps (conical caps) of 3 cm radius and 4 cm height. If the available colour paper sheet is 1000 cm2<\/sup>, then how many caps can be manufactured from that paper sheet?
\nAnswer:
\n\"AP
\nRadius of the cap (conical cap) (r) = 3 cm
\nHeight of the cap (h) = 4 cm
\nSlant height l = \\(\\sqrt{r^{2}+h^{2}}\\)
\n(by Pythagoras theorem)
\n= \\(\\sqrt{3^{2}+4^{2}}\\)
\n= \\(\\sqrt{9+16}\\)
\n= \u221a25

Question 6.
\nA cylinder and cone have bases of equal radii and are of equal heights. Show that their volumes are in the ratio of 3 : 1.
\nAnswer:
\nGiven dimensions are:
\nCone:
\nRadius = r
\nHeight = h
\nVolume (V) = \\(\\frac{1}{3}\\)\u03c0r2<\/sup>h<\/p>\n

Cylinder:
\nRadius = r
\nHeight = h
\nVolume (V) = \u03c0r2<\/sup>h<\/p>\n

Ratio of volumes of cylinder and cone = \u03c0r2<\/sup>h : \\(\\frac{1}{3}\\)\u03c0r2<\/sup>h
