V of cone=(1/3)(pi)(h)(r^2)
V of cylinder=(pi)(h)(r^2)

1.
r=6
h=10
v=(1/3)(pi)(10)(6^2)
v=1/3pi10(36)
v=1/3pi360
v=120pi
answer is B

2.
r=d/2
d=10
10/2=5=r
V=(3.14)(5)(5^2)
V=3.14(125)
V=392.5
answer is B

3. 9.2, 3.7
V=(pi)(9.2)(3.7^2)
V=(pi)(9.2)(13.69)
V=(pi)(125.948)
input 125.948

4. v=(1/3)(pi)(12)(3^2)
V=(1/3)(pi)(12)(9)
V=(pi)(12)(3)
V=pi(36
v=36pi
v=36(3.14)
V=113.04

input 113.04

ANSERS
1.B
2.B
3. 129.948
4. 113.04

Which equation can be used to represent this information?

bogdanovich [222]

Answer:

r=s+5

Step-by-step explanation:

So, letsgo over what we know:

The regular price is r

The sale price is s

Now lets compare the difference between r and s:

10r = 5s

20r = 15s

30r = 25s

What is the difference between the r and s value in each situration?

Well, from what I can see, r is always 5 more than s.

This can be writen as:

r = s+5\

So this is our equation, for if you plug in any number for s, you will get an accurate r value.

For instance, if you say s is 25:

r=25+5

=

r=30

This looks just like the 30r=25s in the table above.

So:

r=s+5

Hope this helps! :)

The graph below shows the distance in miles, m, hiked from a camp in h hours.

Artist 52 [7]

Answer:

Option 1) is correct

Step-by-step explanation:

Given: The graph shows the distance in miles, m, hiked from a camp in h hours.

To find: hourly interval that had the greatest rate of change

Solution:

Rate of change between two points refers to the vertical change divided by the horizontal change.

For hour 0 to hour 1:

rate of change = $\frac{2-0}{1-0}=2$

For hour 2 to hour 3:

rate of change = $\frac{4.5-3.5}{3-2}=1$

For hour 1 to hour 2:

rate of change = $\frac{3.5-2}{2-1}=1.5$

For hour 3 to hour 4:

rate of change = $\frac{5-4.5}{4-3}=0.5$

So, rate of change is greatest in interval: hour 0 to hour 1
