Question 767531
You have a table with a round top that has a diameter of 2 1/2 feet. You would like to put a piece of glass over the top of the table to protect the surface. What is the area of the table top? use 3.14 value of pi. It also says to write it as a mixed number.


Area for circle is {{{pi*(d/2)^2}}} and {{{d/2}}} is the radius. 
Area is {{{3.14*((2&1/2)/2)^2}}}
{{{3.14*((5/2)/2)^2}}}
{{{3.14(5/4)^2}}}
{{{3.14(25/16)}}}
{{{4.90625}}}  square feet

-
but you wanted mixed number units, so 
{{{4+((4.90625-4)*16)/16}}} but do not perform computation with the denominator of 16; you want to form the mixed number result!


ANSWER:   {{{4 & 14.5/16}}}  NOT Quite the way we want. We should use a fractional part with a whole number numerator and denominator, so let's just multiply the fraction by {{{2/2}}} to get
{{{highlight(4 & 29/32)}}} square feet.
