The volume of a cylinder is 30 pie cubic units. A cone shares the same base. The height of the cone is twice the height of the c
bija089 [108]

<u>Given</u>:

The volume of a cylinder is 30 \pi cubic units.

A cone shares the same base.

The height of the cone is twice the height of the cylinder.

We need to determine the volume of the cone.

<u>Height of the Cone:</u>

Let h denote the height of the cylinder.

Let H denote the height of the cone.

Since, it is given that, the height of the cone is twice the height of the cylinder, we have;

H=2h

<u>Volume of the cylinder:</u>

The formula to determine the volume of the cylinder is

V=\pi r^2 h

Since, volume of the cylinder is 30 \pi, we get;

30 \pi = \pi r^2 h -------(1)

<u>Volume of the cone:</u>

The formula to determine the volume of the cone is

V=\frac{1}{3} \pi r^2 H

Substituting H=2h, we get;

V=\frac{1}{3} \pi r^2 (2h)

V=\frac{2}{3} \pi r^2 h

Substituting equation (1), we get;

V=\frac{2}{3} (30 \pi)

V=20 \pi

Thus, the volume of the cone is 20π

Hence, Option C is the correct answer.

Ming wants to make a 40% sugar solution. She had already poured 3 L of a 80% sugar solution into a beaker. How many L of a 10% s
jeyben [28]

Answer:

Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:

if 3 L = 80%

1.5 L should = 40% (since it is half of 80%)

and if 40 divided by 4 = 10%

1.5 also needs to be divided by 4

so 1.5 divided by 4 = 0.375

that means Ming must add 0.375 L of a 10% sugar solution
