The area of the circle is #154# square feet.

The formula for area of a circle is:

#A=pir^2#, where #A=#area, #pi=22/7#, and #r=#radius.

Since we know that the radius is half the diameter of a circle, we know that the radius of the given circle is #14/2=7ft#.

Hence:

#A=pir^2#

#A=22/7xx7^2#

#A=22/7xx7xx7#

#A=22/cancel7xxcancel7xx7#

#A=22xx7#

#A=154#
