Find the area of the given geometric figure. If the figure is a circle, give an exact area and then use 22/7 as an approximation for pie to approximate the area. r=2in

Respuesta :

[tex]\begin{gathered} \text{geometric figure:circle} \\ \text{radius: 2 inches} \\ \pi=\frac{22}{7} \\ \end{gathered}[/tex]

the area of a circle is given by:

[tex]\text{Area}=\pi\cdot radius^2[/tex]

Step 1

replace

[tex]\begin{gathered} \text{Area}=\frac{22}{7}\cdot(2inches)^2 \\ \text{Area}=\frac{22}{7}\cdot4in^2 \\ \text{Area}=\frac{22\cdot4}{7} \\ \text{Area}=12.57 \end{gathered}[/tex]

so, the answer is 12.57 square inches
