Answer:
0.75 gallon
Step-by-step explanation:
3 gallons of batter are poured equally into 4 bowls.
We have to calculate the amount of batter in each bowl.
so we have to divide 3 gallons by 4 to get the answer.
Total amount of batter = 3 gallons
divided into number of bowls = 4
The amount in each bowl = gallons
= 0.75 gallons
0.75 gallon of batter are in each bowl.
Answer:
Volume:
Ratio:
Step-by-step explanation:
First of all, we need to find the volume of the hemispherical tank.
The volume of a sphere is given by:
where
r is the radius of the sphere
V is the volume
Here, we have a hemispherical tank: a hemisphere is exactly a sphere cut in a half, so its volume is half that of the sphere:
Now we want to find the ratio between the volume of the hemisphere and its surface area.
The surface area of a sphere is
For a hemisphere, the area of the curved part of the surface is therefore half of this value, so . Moreover, we have to add the surface of the base, which is
. So the total surface area of the hemispherical tank is
Therefore, the ratio betwen the volume and the surface area of the hemisphere is
