Question

find the area of the circle. write your answer using \pi\ with no spaces.

\\(a_{\text{circle}} = \\) \\(\text{km}^2\\)

Explanation:

Calculate the radius of the circle

$$ r = \frac{d}{2} = \frac{14\text{ km}}{2} = 7\text{ km} $$

Calculate the area of the circle

$$ A = \pi r^2 = \pi (7)^2 = 49\pi\text{ km}^2 $$

Answer:

Find the area of the circle. Write your answer using "pi" with no spaces.

\(A_{\text{circle}} =\) <blank>49pi</blank> \(\text{km}^2\)
