Answer 2

Answer:

Given:

•      volume of a hemisphere = 18000πcm³

To find :

  diameter of hemisphere

Pre-requisite knowledge :

  volume of hemisphere = $\dfrac{2}{3}\pi r^3$

Solution:

substitute the values in the equation;

$\dfrac{2}{3}*\dfrac{22}{7} *r^3 = 18000\pi\\\\\implies \dfrac{2}{3}*r^3=18000\\\\\implies r^3= 27000 \implies\bold{ r=30}$

Thus, r = 30cm

hence diammeter of it is 2*30 = 60 cm
