8. Find the volume of the cone pictured. (Give your answer correct to 2 decimal places.)
Answers
1. First the base of the cone
Pii*radius*radius
3.14*10*10 which equals 314
2. Now multiply 314 and 14 and you should get 4396
3. Now divide by 3 and you should get 1465.33
Note: the answer is 1465.33333333333 but I just moved it to 2 decimal places.
Hope this helps if so mark me the brainiest!!

Answers
Answer:
Number one the base is 24 and the Volume is 120
Number two the base is also 24 and the Volume is 240.
Step-by-step explanation:
For #1:
For the first one the area of the base is 8x3 which equals 24 so for base Number 1 its 24.
All we got to do to figure out the volume is multiply by 10 *the height* and then divide by 2 because we are finding the volume of a pyramid. 24x10 = 240/2 = 120. So the volume for Number 1 is 120.
For #2:
It has the exact same number except we are dealing with a rectangular prism which means at the end we don't have to divide by 2. For the base its 8 x 3 = 24 the same as the pyramid. For the volume- 8 x 3 = 24 x 10 = 240 which means the volume is 240. And of course don't forget the unit yards³

The histogram shows the number of items sold at The Clothes Horse one week. About what percent of items sold cost less than $40
A. 55%
B. 56%
C. 34%
D. 25%
Answers
because if you were to add up all the frequencies together of each price range it would be 320 and the total frequency that cost less than $40 is 110, so if you divide 110 and 320 you’d get a decimal of 0.34 which is 34%

You asked amusement park visitors the question “How many times did you ride the Ferris wheel today?” as they left the park.
Four people said they rode a Ferris wheel 5 times. Explain how this would be shown on a dot plot.
Answers
Answer:
Draw an xy axis. On the x-axis, put "number of times person rode the Ferris wheel" or something along those lines. For the y axis, put "frequency". For x = 5, you'll have four dots stacked on top of each other at this x value. I suggest having a slight gap between each dot so you can tell them apart. The four dots represent the four people who said they rode the Ferris wheel five times.

Answer:
Step-by-step explanation:
Plug in each number:
For A. you will do this: 2*78 + 6 = 156 + 6 = 162. So, no. You need 90 degrees.
For B. you will do this: 2*72 + 6 = 144 + 6 = 150. So, no. You need 90 degrees.
For C. you will do this: 2*42 + 6 = 84 + 6 = 90. This is a possible answer choice, but you should keep going just in case.
For D. you will do this: 2*36 + 6 = 72 + 6 = 78. So, no because you need 90 degrees for a right angle. (A right angle is 90 degrees)

30. Consider the diagram below. Solve for x.
Answers
Answer:
x = 111°
Step-by-step explanation:
The 2 vertical lines are parallel.
So the sum of the 2 interior angles are equal to 180°.
x + 69° = 180°
x = 111°
Using the diagram, find all the angle measures when the measure of angle XUY=40degrees
Answers
Answer:
XUY = 40 degrees
WUZ = 90 degrees
XUZ = 50 degrees
VUW = 40 degrees
VUY = 140 degrees
I hope this helps :)
Step-by-step explanation:
WUZ is a right angle, so 90 degrees. YUW is a straight angle, so it is 180 degrees, so WUZ + XUZ + XUY = 180, WUZ is 90 and XUY is 40, so 90 + 40 = 130, 180 - 130 = 50
XUZ is 50 degrees
Since VUW is on the opposite side of XUY, it is the same degrees as it, so VUW is 40 degrees
YUW is 180 degrees, so VUW + VUY = 180, VUW is 40 degrees, so VUY is 180 - 40 = 1400, VUY is 140 degrees
Now we have them all:
XUY = 40 degrees
ZUW = 90 degrees
XUZ = 50 degrees
VUW = 40 degrees
and finally,
VUY = 140 degrees
Reading this whole thing, it sounds sooo weird

Step-by-step explanation:
45/360 covers about 1/8 of the entire degress of a circle, this means the image that corresponse with be on the smaller side.
a- this seems closer to 1/4 and would not be the best match
b- this covers half, so this is much to large to correspond
c- this is the closest eyballing it, as it looks small enough to cover 1/8th as well as be properly notated
d- this is smaller and could be correct except the notation on it shows that it is going around the outside (so 360- that angle)

Find the radius of a sphere with a volume of 972π cubic millimeters.
Answers
Answer:
The radius is 9 mm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3 where r is the radius
972 pi = 4/3 pi r^3
Divide each side by pi
972 = 4/3 r^3
Multiply each side by 3/4 to isolate r^3
3/4 * 972 = 4/3 * 3/4 r^3
729 = r^3
Take the cube root of each side
(729) ^ (1/3) = (r^3) ^ (1/3)
9 = r
The radius is 9 mm
Answer:
9 mm
