Correct Answer: 4158

Solution : Let $r$ be the radius of the hemisphere.
Volume of a hemisphere, V = $\frac{2}{3} \pi r^3$
Given: V = $19404$
⇒ $19404 = \frac{2}{3} \pi r^3$
⇒ $19404 = \frac{2}{3}\times \frac{22}{7}\times  r^3$
⇒ $r^3= 9261$
⇒ $r = 21\ \text{cm}$
Total Surface Area of

Correct Answer: $3 \sqrt 3\text{ cm}$

Solution :
The side of an equilateral triangle ($a$) $=9\text{ cm}$
Median $AD$ of equilateral triangle $=\frac{\sqrt{3}}{2}a$
⇒ ${AD} = \frac{\sqrt{3}}{2}\times 9$
Also, a centroid divides the median in the ratio of $2:1$.
So, $ AG : GD = 2 : 1$
⇒ $\frac{AG}{AD}=\frac{2}{3}$
