A. A 5in radius ball is in a

abruzzese [7]

Answer:

52.33%

Step-by-step explanation:

Since, all six sides of the box are touching the ball.

So, all the three dimensions of the box are equal.

Hence, it is a cubical box.

Side length of the box (l)

= diameter of the ball

= 2*radius of the ball

= 2*5

= 10 In.

$V_{ball} = \frac{4}{3} \pi r^3$

$V_{ball} = \frac{4}{3} \times 3.14(5)^3$

$V_{ball} = \frac{4}{3} \times 3.14\times 125$

$V_{ball} = \frac{1,570}{3}\: In^3$

$V_{box} =l^3$

$V_{box} =(10)^3$

$V_{box} =1000\: In^3$

Percentage of the space in the box occupied by the ball

$= \frac{V_{ball}}{V_{box} } \times 100$

$= \frac{\frac{1,570}{3}}{1000} \times 100$

$= \frac{1570}{3000} \times 100$

$= \frac{157}{3}$

$= 52.33\%$

Berikut ini adalah data hasil penjualan beras toko “Sukses” selama seminggu (dalam kg). 24, 23, 25, 30, 31, 23, 26, 25, 29, 27,

Gnoma [55]

The mode of the given data is 25.

<u>Explanation:</u>

24, 23, 25, 30, 31, 23, 26, 25, 29, 27, 26, 25, 26, 25, 24, 27, 28, 30, 25, 27, 30, 26

Rearranging the data in ascending order:

23, 23, 24, 24, 25, 25, 25, 25, 25, 26, 26, 26, 26, 27, 27, 27, 28, 29, 30, 30, 30, 31

Mode of a data is the number that is repeated the most number of times in the entire data set.

From the given data set, we can see that the number that is repeated the maximum number of times is 25 as 25 is repeated 5 number of times.

Thus, the mode of the given data is 25.
