Answer:

12.86 cm³ of water is saved

Step-by-step explanation:

✔️Since width of new ice ball must be the same as the length of original cube, therefore, diameter of the ice ball = 3 cm

Radius of ice ball = ½(3) = 1.5 cm

Volume of the new sphere ice ball = ⁴/3πr³

Substitute

Volume of new sphere ice ball = ⁴/3 × π × 1.5³ = 14.14 cm³

✔️To find out how much water would be saved using the new sphere ice ball, let's find the volume of the cube then find the difference of both.

Volume of original ice cube with length 3 cm:

Volume of cube = s³

s = 3 cm

Volume of cube = 3³ = 27 cm³

Volume of water saved = 27 cm³ - 14.14 cm³

= 12.86 cm³

Answer:

P * 300000 = 30

.01%

Step-by-step explanation:

Let P equal the percent. Of means multiply and is means equals

We need to make sure the units are the same. I will convert km to cm

3 km *1000m/1km * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %
