Answer:

The area of this plate is
$36.31\ \text{inches}^2$ .

Explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

$C=2\pi r$

r is radius of circular shape

$r=(C)/(2\pi)\\\\r=(21.4)/(2* 3.14)\\\\r=3.4\ \text{inches}$

Area of this plate is given by :

$A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2$

So, the area of this plate is
$36.31\ \text{inches}^2$ .
