<PRE><B>Question 210243</B>
What is the area in feet of a circular table cloth that has a diameter of 42 inches?
:
We use the radius here: 42/2 = 21 inches
:
A = {{{pi*r^2}}}
A = {{{pi*21^2}}}
A = {{{441*pi}}} sq/inches
:
There are 144 sq/in in 1 square ft
:
{{{(441*pi)/144}}} = {{{3.0625*pi}}} sq/ft
