By definition, the volume of a cone is given by:

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

Where,

r: radius of the circular base

h: height of the cone

Since we have 6 conical pots, then the total volume is:

Vt=6V

Vt = 6 * (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)

Substituting values we have:

Vt = 6 * (\frac{1}{3}) * (3.14) * (3 ^ 2) * (8)\\Vt = 452.16 cm ^ 3

Rounding to the nearest cubic centimeter:

Vt = 452 cm ^ 3

Answer:

are needed 452 cm^3 of soil to plant the full tray

Hey everyone I need help on the questions please!:)​
Aneli [31]

Answer:

a. 1/2

b. 1 hair cut

c. 2.5

Step-by-step explanation:

4/8 divde by 4 to simplify and that gets you 1/2

8/4 is 2 so he does one hair cut every two hours

so you know how many he can do in 2 hours so add it up. It’s going to be 2 people in four hours so it will be half a hair cut in 5 hours

Data management:<br><br> Find n if <br><br> C ( n+ 2 , 2 ) = 36
Lana71 [14]
Please, Karla, explain what "C" and "n" represent.  Are you talking about combinations (for example, n+2 objects taken n at a time?  Or is C some kind of function?  I don't quite see the relationship of this problem to 'data management.'

The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!

What is the true solution In 20+In 5=2 In x?
S_A_V [24]

Answer:

x = 10

Step-by-step explanation:

Using the rules of logarithms

• log x + log y ⇔ log(xy)

• logx^{n} ⇔ n log x

• log x = log y ⇒ x = y

Given

ln20 + ln5 = 2 lnx , then

ln(20 × 5) = lnx^{2}

ln 100 = lnx^{2}, hence

x² = 100 ( take the square root of both sides )

x = 10
