Calculate the area of the provided figure.

$361\pi\textup{ in}^2$

$360\pi\textup{ in}^2$

$362\pi\textup{ in}^2$

$363\pi\textup{ in}^2$

$364\pi\textup{ in}^2$

In order to solve this problem, we need to recall the area formula for a circle:

$A=r^2\pi$

Now that we have the correct formula, we can substitute in our known values and solve:

$A=19^2\pi$

$A=361\pi\textup{ in}^2$

Calculate the area of the provided figure.

$144\pi\textup{ in}^2$

$143\pi\textup{ in}^2$

$142\pi\textup{ in}^2$

$141\pi\textup{ in}^2$

$140\pi\textup{ in}^2$

In order to solve this problem, we need to recall the area formula for a circle:

$A=r^2\pi$

Now that we have the correct formula, we can substitute in our known values and solve:

$A=12^2\pi$

$A=144\pi\textup{ in}^2$
