#50.24# in; #16pi# in

The area of a circle is given by

#pir^2#

Where #r# is the radius and #pi~~3.14#, the ratio of a circle's circumference to its diameter.

Plugging in #4# from the radius, we get

#4^2pi#

#=>16pi# inches

This is our exact answer. Alternatively, we can plug in #3.14# for #pi# to get

#50.24# inches

Hope this helps!
