Question

finding area find the area of the figure. 29. image of a circle on a coordinate grid with y-axis (up to 2), x-axis, and center marked

Explanation:

Step1: Determine the radius

From the grid, we can see that the radius \( r \) of the circle is 2 units (since it spans 2 grid squares from the center to the edge).

Step2: Use the area formula for a circle

The formula for the area of a circle is \( A = \pi r^2 \). Substituting \( r = 2 \) into the formula:
\( A=\pi\times(2)^2 \)

Step3: Calculate the area

Simplify the expression: \( A = 4\pi \) (or approximately \( 12.57 \) if using \( \pi\approx3.14 \))

Answer:

The area of the circle is \( 4\pi \) (or approximately \( 12.56 \)) square units.
