Answer: Area of the plate = 21.23 inches squared
The diameter of the plate = 5.2 inches
[tex]\begin{gathered} \text{Area = }\pi\cdot r^2 \\ \text{r = }\frac{diameter}{2} \\ \text{r = 2.6 inches} \\ \pi\text{ = 3.14} \\ \text{Area = 3.14 }\cdot2.6^2 \\ \text{Area = 3.14 x 6.76} \\ \text{Area = 21.23 square inches} \end{gathered}[/tex]
