Question

24The figure shows a circle graphed on a coordinate planeWhat is the approximate circumference of the circleА126 unitsB25 1 unitcD50 units

Answer 1

From the figure, the coordinates center of the circle is (x, y)=(-1, -2).

The horizontal distance from the center of the circle to one point of the circle gives the radius of the circle.

So, the radius of the circle is r=4.

Now, the circumference of the circle can be calculated as,

`\begin{gathered} C=2\pi\text{ r} \\ =2\pi*4 \\ =25.1\text{ units} \end{gathered}`

Therefore, the approximate circumference of the circle is 25.1 units.

Option B is correct.
