If the diameter of the circle below is 16 in., what is the area of the circle?

mote1985 [20]

Answer:

64π inches² (approximately 201.06 inches²)

Step-by-step explanation:

$A=\pi r^2$ where $r$ is the radius

To find the radius, divide the diameter by 2

16 ÷ 2 = 8 inches

Plug in 8 as the radius

$A=\pi (8)^2\\A=64\pi$

$A=201.06$ (approximately)

Therefore, the area of the circle is 64π inches², or approximately 201.06 inches².

I hope this helps!

Q3. Consider two identical pack of cards A and B. When one card from A is taken and shuffled with the card B, the first top card

vivado [14]

Answer:

0.02

Step-by-step explanation:

Pack A and B both consisted of 52 cards. When shuffled, 51 cards in A and 53 cards in deck B. It appears that the Top card of A left with only 51 possible cards to be taken from A (since we know the Queen hadn't moved).

The two possible cases are: probability of not taking King of Hearts (from A to B), and the other were we did.

Let K= the event of taking the King of Hearts from A to B and be $B_{K}$ the occasion being the top card of B.

$P(B_{K} )=P(K)P(B_{K} |K)+P(K^{C} )P(B_{K} |K^{C} )\\$

$=\frac{1}{51} \frac{2}{53} +\frac{50}{51} \frac{1}{53}$

$=\frac{52}{2703} \\=0.02$
