Question

given the two concentric circles with center m below, km = 11.5. find the area of the shaded region. round your answer to the nearest tenth if necessary. answer attempt 1 out of 3

Explanation:

Step1: Identify outer radius R

$R = 11.5$

Step2: Identify inner radius r

$r = 9$

Step3: Compute area difference

$\text{Shaded Area} = \pi(R^2 - r^2)$

Step4: Calculate and round

$\pi(11.5^2 - 9^2) = \pi(132.25 - 81) = 51.25\pi \approx 161.0$

Answer:

161.0
