Question 74519
If the radius of a circle is .25, what is the area? I came up with .19634. How can that be?
.
Your answer is close enough. A few more decimal points would give you the answer 0.1963495
and that would round to 0.19635.
.
What's probably causing you to wonder about it is the radius.  In fractional form, the radius
is:
.
{{{1/4}}} and when you square that in calculation {{{pi*r^2}}} the square of the radius becomes
{{{1/16}}}. When you multiply {{{pi}}} by the radius squared, you are actually dividing
{{{pi}}} by {{{16}}}.  That's what causes the Area to be very small (and when you think about
it, a circle with a radius 0.25 is a pretty small circle, so you might expect its Area
to be small also).
.
Hope this helps to get rid of your concern.  You did the problem correctly. Good job!!!!
