#~~134# square inches.

Explanation:

Assuming the plate is a perfect circle, then we can solve accordingly.

The circumference of a circle is given by:

#C=2pir#

where:

  • #r# is the radius of the circle

So, we get:

#r=C/(2pi)#

#=(41 \ "in")/(2pi)#

#~~6.53 \ "in"#

The area of a circle is given by:

#A=pir^2#

And so, the area of this plate will be:

#A=pi*6.53^2#

#~~134 \ "in"^2#
