ANSWER

132.7 km^2 option B

Step-by-step explanation

Step 1: Formula for Area of a Circle


\text{Area of a circle = }\pi r^2

where radius r = diameter/2

r = 13/2

r = 6.5km

Step 2: Substitute the values of r = 6.5 and pi = 3.14


\begin{gathered} \text{Area = }\pi r^2 \\ \text{ = 3.14 }*6.5^2 \\ \text{ = 3.14 }*\text{ 42.25} \\ \text{ = }132.665\text{ }=\text{ 132.7 }km^2\text{ (to nearest tenth)} \\ \end{gathered}

Hence, the area of the circle with radius 6.5km is 132.7km^2 (to the nearest tenth).
