At first, the beat needed to be more than ten seconds, so the beat could be more than or equal to 11 seconds. then, the beat has to be five seconds more than that, so the beat has to be more than or equal to 16 seconds.
so the beat could be 16 ≤ 17 seconds, 16 ≤ 18 seconds, or 16 ≤ 100 seconds. as long as it's more than 16 seconds it would work.
<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>
