To find the volume of a cylinder, start with the formula for the volume of a cylinder.
Volume =
Notice that our cylinder has a radius of 7 and a height of 16. So we have
() (7)
(16)
Let's start by simplifying the exponents. ≈ 49
() (49) (16)
49 × 16 = 784
We can add a unit so we have 784.
Answer:
6 liters.
Step-by-step explanation:
So we have a glass, a jar, and a pitcher and together, they hold 54 liters.
We are told that the jar has the same volume as 3 glasses and the pitcher has the same volume as 5 glasses. In other words, let g denote glasses, j denote jars, and p denote pitchers:
Since jar is the same as 3 glasses, this means that j=3g. And since the pitcher is the same as 5 glasses, this means that p=5g. Substitute:
Combine like terms:
Divide both sides by 9. The left cancels:
Therefore, the volume of the glass is 6 liters.
