The volume of globe is 381.51 cubic inches when the dimensions of the globe were reduced by half
<em><u>Solution:</u></em>
The globe is usually of spherical shape
<em><u>The volume of sphere is given as:</u></em>
![V = \frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3)
Where, "r" is the radius of sphere
Given that diameter is 18 inches
Diameter = 18 inches
![Radius = \frac{diameter}{2}\\\\Radius = \frac{18}{2} = 9](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cfrac%7Bdiameter%7D%7B2%7D%5C%5C%5C%5CRadius%20%3D%20%5Cfrac%7B18%7D%7B2%7D%20%3D%209)
Thus radius is 9 inches
The dimensions of the globe were reduced by half
Thus radius is reduced by half
![Radius = \frac{9}{2} = 4.5](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cfrac%7B9%7D%7B2%7D%20%3D%204.5)
Now find the volume of sphere
![V= \frac{4}{3} \times 3.14 \times 4.5^3\\\\V= 4 \times 3.14 \times 30.375\\\\V = 12.56 \times 30.375\\\\V = 381.51](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%203.14%20%5Ctimes%204.5%5E3%5C%5C%5C%5CV%3D%204%20%5Ctimes%203.14%20%5Ctimes%2030.375%5C%5C%5C%5CV%20%3D%2012.56%20%5Ctimes%2030.375%5C%5C%5C%5CV%20%3D%20381.51)
Thus volume of globe is 381.51 cubic inches
Answer:
Less than one : options 1 and 2
Equal to one : option 3
Greater than one : options 4, 5, and 6
Step-by-step explanation:
B. 30
$39(4) + $34.30 = $1200
$156 + 34.30 = $190.30
$1200 - $190.30 = $1009.70
$1009.70 / $34.30 = 29.437
