Question 1163460
<br>
If the volumes and the heights are both equal, then the areas of the bases are equal.<br>
The area of the base of the cone is {{{pi(r^2)}}}; the area of the base of the pyramid is 154 sq cm.  So<br>
{{{(22/7)(r^2) = 154}}}
{{{r^2 = 154(7/22) = 7*7}}}
{{{r = 7}}}<br>
ANSWER: The radius of the base of the cone is 7cm.<br>
