You need to know how to calculate the volume of a cylinder and how to calculate the volume of a cone. We know that the two things have the same height and they also have the same area for their base.

Let's say that the area of the base is x.

The volume of the cylinder = x * 30 (area of the base multiplied with the height)

The volume of the cone = x/3 * 30 (1/3 multiplied with the area of the base and the height)

This means that the cone has one third of the volume of the cylinder's. Therefore if I pour water from a full cone, I can fill the cylinder only to the third of its volume, and in this case, height. So the answer is 10 cm.

Elaina wrote two correct variable expressions to represent the phrase “one-fourth of a number.” Which variable expressions could Elaina have written? Select each correct answer. A.) 4 ÷ n
B.) 4/n
C.) 1/4n
D.) n4

Answers

Answer:

$(1)/(4)n$

$(n)/(4)$

C and D are correct options.

Step-by-step explanation:

The given phrase is “one-fourth of a number.”

Let the number be n.

one fourth means 1/4

Hence, the phrase “one-fourth of a number.” can be written as

$(1)/(4)n$

We can rewrite this expression by multiplying numerator as

$(n)/(4)$

Therefore, the required expressions are

$(1)/(4)n$

$(n)/(4)$

C and D are correct options.

1/4n, and also D IF it's n/4.
