mary wants to fill in a cylinder vase. the flower store told her to fill the vase 4/5 of the way for the flowers to last the lon
Goshia [24]

Volume is a three-dimensional scalar quantity. The volume of the water that Marry should pour into the vase is 241.28 cubic inches.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the radius of the flower vase is 4 inches, while the height of the vase is 6 inches, therefore, the total volume of the vase is,

Volume = πR²×H = π× 4²×6 = 301.6 in³

Since the volume of the vase is 301.6 in³, but the store has told her to fill the vase 4/5 of its capacity, therefore, the volume of water Marry should pour is,

Volume of water = (4/5) × 301.6 in³ = 241.28 cubic inches

Hence, the volume of the water that Marry should pour into the vase is 241.28 cubic inches.

Mark had $436. chris has $86 less than mark.write an expression to show how much money chris actually had
Nikitich [7]

We have been given that Mark had $436.

Further, we are given that Chris has $86 lesser than what mark had.

Let us assume that Chris has $x. Therefore, we can set up an equation:

(Amount Chris had) + $86 = (Amount Mark had)

x+86=436

Upon subtracting 86 from both the sides, we get:

x=436-86

Therefore, the required expression that represent the amount of money that Chris had is 436-86.
