<h3><u>Part A</u></h3>
To show the total capacity of container B is 132 cm³
volume = unit rate × time taken
volume = 6 cm³ × 22
volume = 132 cm³ ∴ Hence proved.
<h3 /><h3><u>Find radius</u></h3>

===================

<em>simplify</em>

<em>change sides</em>

<em>square root both sides</em>
∴ Hence the radius of cone (Shape B is 3 cm)
<h3><u>To show the time taken</u></h3>
volume = unit rate × time taken

=========================

<em>Insert values</em>

<em>exchange sides</em>

<em>simplify following</em>
