To solve this we are going to use the formula for the volume of a sphere:
where
is the radius of the sphere
Remember that the radius of a sphere is half its diameter; since the first radius of our sphere is 24 cm,
. Lets replace that in our formula:
Now, the second diameter of our sphere is 36, so its radius will be:
. Lets replace that value in our formula one more time:
To find the volume of the additional helium, we are going to subtract the volumes:
Volume of helium=
We can conclude that the volume of additional helium in the balloon is
approximately <span>
17,194 cm³.</span>

Answer:
A. Channing makes $8.55 an hour compared to Tyrell who only makes $8 an hour.
Step-by-step explanation:
To find how much Channing makes an hour, divide the amount earned ($42.75) by the hours he worked (5). So, 42.75/5=8.55 which is Channing's hourly wage. Tyrell's hourly wage was already given to us in the equation E=8h. 8 times his hours works= his earnings. 8.55>8.00
