A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The

frez [133]

Considering the area of the hole, it is found that there is a 4.9% probability of hitting a ball into the circular hole.

<h3>What is the area of a circle?</h3>

The area of a circle of radius r is given by:

$A = \pi r^2$

In this problem, the hole has a diameter of 1 ft, hence it is radius is of r = 1 ft/2 = 0.5 ft, and it's area is given by:

$A = \pi \times (0.5)^2 = 0.7854 \text{ft}^2$

Hence the probability is given by:

p = 0.7854/16 = 0.049 = 4.9%

Decide whether you would use a permutation, a combination, or neither. Next, write the solution using permutation notation or co

Zepler [3.9K]

Answer:

Permutation is used.

No. of arrangements = 1260

Step-by-step explanation:

Permutation is used for choosing & arrangement of 'r' out of 'n' objects, when sequence is important.

Total no. of alphabets in CORRECT = 7

C is repeated twice, R is repeated twice

So, Total No. of arrangements = 7 !

(2!)(2!)

= 5040 / 4

= 1260
