Answer: 3053.6 cubic cm

Step-by-step explanation:

The volume of sphere is given by :-

$\text{Volume]=\dfrac{4}{3}\pi r^3$ , where r is the radius of the sphere.

Given: The diameter of sphere = $d=18\ cm$

Then , the radius of the sphere = $r=\dfrac{18}{2}=9\ cm$

Now, the volume of the sphere will be ;_

$\text{Volume}=\dfrac{4}{3}(3.14159265359) (9)^3\\\\\Rightarrow\text{Volume}=3053.62805929\approx3053.6\text{ cubic cm}$

Lauren in making 15 liters of mimosas for a brunch banquet. Orange juice costs her $1.50 per liter and champagne costs her $12 p

PSYCHO15rus [73]

Answer:

10 liters of orange juice
5 liters of champagne

Step-by-step explanation:

Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...

12c +1.50(15-c) = 5.00(15)

10.5c = 52.50 . . . . . subtract 22.50, simplify

52.50/10.5 = c = 5 . . . . divide by the coefficient of c

Then the amount of orange juice is ...

15 -c = 15 -5 = 10 . . . . liters

Lauren should use 5 liters of champagne and 10 liters of orange juice.
