Question

The volume of a right circular cone is 9856cm.if the ra-
-dius of the base is 14cm then find the height of cone
(use J
$\pi$
=22/7)​

Answer 1

$Given: \\ r= \frac{28}{2} =14cm \\ Let \: height =h \\ ⇒Volume =9856= \frac{1}{3} πr {}^{2} h \\ 9856= \frac{1}{3} × \frac{22}{7} ×14×14×h \\ ⇒h=48cm$

$\sf{Hence \: the \: height \: is \: 48cm}$
