Question

(14) find the circumference of the circle. round your answer to the nearest tenth.

Explanation:

Step1: Identify the radius of the circle

From the graph, the radius \( r = 4\) (assuming the distance from the center to the edge is 4 units as per the grid - if we assume each grid square is 1 unit. If we consider the center at \((5,0)\) and the right - most point at \((9,0)\), \(r=9 - 5=4\))

Step2: Use the formula for the circumference of a circle

The formula for the circumference of a circle is \(C = 2\pi r\). Substitute \(r = 4\) into the formula: \(C=2\pi\times4=8\pi\)

Step3: Calculate the numerical value and round

\(C = 8\pi\approx8\times3.14 = 25.12\approx25.1\)

Answer:

\(25.1\)
