Correct Answer: 5 : 14

Solution : Given,
Slant height($l$) = 29 cm
Height($h$) = 20 cm
⇒ Radius, $(r) = \sqrt{l^2-h^2}$
⇒ $r=\sqrt{29^2-20^2}$
⇒ $r=\sqrt{841-400}$
⇒ $r=\sqrt{441}$
⇒ $r=21$ cm
Total surface area of cone = $ πr(r + l)$ and volume = $\frac13πr^2h$
$\therefore$ Ratio = $(r+l):(\frac13rh)=(21+29):\frac13\times21\times20=50:140=5 :

Correct Answer: 185

Solution : Given: 
83, 100, 134, ?, 253
