Mary should pour around 3.7 liters or 226.08 in³ volume of water in the vase.
Given Information and Formula Used
Radius of the cylindrical vase, r = 3 inches
Height of the cylindrical vase, h = 8 inches
The formula for the volume, V of a cylinder is given as,
V = πr²h
Here, r is the radius of the cylinder and h is the height of the cylinder.
Calculating the Volume
Substituting the given values of r and h in the formula for the volume of cylinder, we get
Volume, V = π(3)²(8)
Using π = 3.14, we have,
V = 3.14(9)(8)
V = 226.08 cubic inches
Volume in Liters
Since, 1 Liter = 61.0237 cubic inches,
1 cubic inch = 1/61.0237 liters
⇒ 226.08 cubic inches = 226.08/61.0237 liters
⇒ 226.08 cubic inches ≈ 3.07 liters
Thus, Mary needs to pour approximately 3.07 liters volume of water in the vase.
