Question

Dinner plate has a diameter of 8 inches. what is the plate's area?

Answer 1

The plate is a circle.

diameter = 8 inches

`\begin{gathered} \text{area}=\pi r^2 \\ \text{where} \\ r=\text{radius}=(8)/(2)=4\text{ inches} \\ \text{area}=\pi*4^2 \\ \text{area}=16\pi \\ \text{area}=(22)/(7)*16 \\ \text{area}=(352)/(7)=50.2857142857 \\ \text{area}=50.30inches^2 \end{gathered}`
