A cone shaped roof has a diameter of 12 feet a height of 8 feet and a slant of the roof is 10 feet if the roofing cost a total o

vitfil [10]

Answer:

$c = 16.392\,\frac{USD}{ft^{2}}$

Step-by-step explanation:

The surface area of the cone shaped roof is:

$A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)$

$A_{s} \approx 188.496\,ft^{2}$

The cost of roofing per square feet is: (USD stands for US dollar)

$c = \frac{3089.76\,USD}{188.496\,ft^{2}}$

$c = 16.392\,\frac{USD}{ft^{2}}$

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

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

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

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

$= \frac{157}{3}$

$= 52.33\%$
