Answer:

#approxcolor(blue)(113# square feet

Explanation:

The area of a circle is given by formula:
#color(blue)(pir^2#
Where,
#pi# has a constant value of #approx3.14#
and #r# denotes the radius.

The radius of the circle is #r= 6#ft

The area #= pir^2 approx 3.14 xx (6)^2#

#approx3.14 xx (36)#

#approx113.04# square feet

#approxcolor(blue)(113#square feet
