the volume of a cylinder is 54 Pi centimeters to the third if the radius is 3 cm what is the height of the cylinder

1 answer:

6 0

The height of the cylinder is 6 cm.

If the volume of the cylinder is 54π cm³, and we know the radius, we can use the formula for the volume of a cylinder to figure out the length of the height.

V = πr²h

Substitute

54π = 9hπ

Divide each side by π
54 = 9h

Get h by itself

h = 6, which means that the height of the cylinder is 6 cm.

How do you complete this One-Step equation? 5 1/2 + p = 6

dalvyx [7]

5 1/2 + p = 6

subtract 5 /12 from each side

5 1/2 - 5 1/2+ p = 6 - 5 1/2

p = 6 - 5 1/2

borrow from the 6

p = 5 2/2 - 5 1/2

p = 1/2

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?

lidiya [134]

Answer:

The total fluid you have to drink is 10 7/10 = 10.7 cups.

Step-by-step explanation:

The daily requirement of water = 8 2/4 cups

Now, $8 \frac{2}{4} = 8+ \frac{2}{4} = 8+ 0.5 = 8.5$

or, the daily water requirement = 8.5 cups

The daily requirement of milk = 2 1/5 cups

Now, $2 \frac{1}{5} = 2+ \frac{1}{5} = 2+ 0.2 = 2.2$

or, the daily milk requirement = 2.2 cups

So, The total fluid needed = Cups of (Water + Milk) needed

= 8.5 cups + 2.2 cups

= 10.7 cups

Also, $10.7 = 10 + 0.7 = 10 + \frac{7}{10} = 10\frac{7}{10}$

Hence, the total fluid you have to drink is 10 7/10 cups.
