The volume of the container is 5969 cm³. The correct option is D. 5,969 cm³

<h3>Calculating Volume </h3>

From the question, we are to determine the volume of the container

Volume of the container = Volume of the cone - Volume of the small cone

The volume of a cone is given by the formula,

V = 1/3πr²h

Where V is the volume

r is the radius

and h is the height

From the given information,

For the small cone,

Diameter = 10 cm

∴ Radius, r = 10cm/ 2 = 5 cm

h = 6 cm

For the big cone

diameter = diameter of the container = 30 cm

∴ Radius = 30cm/ 2

Radius = 15cm

h = height of small cone + height of container

h = 6 cm + 20 cm

h = 26 cm

Putting the parameters into

Volume of the container = Volume of the cone - Volume of the small cone

We get,

Volume of the container = 1/3π × 15² ×26 - 1/3π × 5² × 6

Volume of the container = 1/3π (15² ×26 -  5² × 6)

Volume of the container = 1/3π (5850 -  150)

Volume of the container = 1/3π (5700)

Volume of the container = 1/3 × π × 5700

Volume of the container = 5969.026 cm³

Volume of the container ≈ 5969 cm³

Hence, the volume of the container is 5969 cm³. The correct option is D. 5,969 cm³

In the rhombus m1 = 10x, m2 = x + y, m3 = 18z. Find the value of each variable
Blababa [14]

I think the question is missing some details. I found a similar question with an image as i attached in this question.

From this image, it its clear that m1, m2 and m3 refers to the angles in the middle of the rhombus

Answer:

x = 9

y = 81

z = 5

Step-by-step explanation:

Note that in rhombus, all sides are the same. If the diagonal lines are made, it will create 4 division of angles of 90 degrees.

Therefore m1 = m2 = m3 = 90 degrees

m1 = 10x and m1 =90

So, 10x = 90. Rearrange it to get x = 90/10 = 9

x = 9

m2 = x + y and m2 = 90

So, x + y = 90

9 + y = 90

y = 90 - 9 = 81

m3 = 18z and m3 = 90

So, 18z = 90

z = 90/18 = 5
