Answer:

379.94 in.²

Step-by-step explanation:

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

$a=\pi r^2$

In the image, the diameter is shown.

To find the radius of a circle, divide the diameter by 2.

$22/2=11$

The radius of this circle is 11 inches.

Next, multiply the radius by itself twice.

$11*11=121$

Lastly, multiply the product by pi (3.14).

$121*3.14=379.94$

Therefore, the area of this circle is 379.94 inches squared.

Step-by-step explanation:

the reason that it would be 3/13 is because its simplified from 12/52, which is 12 of the possibly of face cards over 52 the amount of cards in the deck, so the possibility was 12/52, but simplified would be 3/13 ! love you !
