Answer:

The volume of the cone is 108π(pi). if the height is 9

Step-by-step explanation:

V = πr2h / 3     (formula for finding the volume)

V = π62(9) / 3

V = 324π / 3

V = 108π

You can change the value of height if its different for you

Omg this is hard plz help

Answer:

257/2

Step-by-step explanation:

So in condition we need to know π=180 so when you multiply by π/180 or 180/π is one

it says we need to change from radian to degree so we need time 180/π

so it like this:

(257π)/360*(180/π)=257/2.

Someone help me please and explain how you got your answer.
zimovet [89]
*I'm not exactly sure what it means by compare the percents of change*

From 2000 to 2005, that's 5 years.
After 5 years, the population decreased from 4.3 mil to 3.2 mil; 3.2 - 4.3 = -1.1; that's a decrease of 1.1 mil.
1.1 mil out of 4.3 mil is approximately 26%.
So from 2000 to 2005, the population decreased by 26%.

From 2005 to 2010, that's also 5 years.
After that 5 years, the population increased from 3.2 mil to 5.6 mil; 5.6 - 3.2 = 2.4; that's an increase of 2.4 mil. 2.4 mil out of 3.2 is 75%.
So from 2005 to 2010, the population increased by 75%.

In a lab experiment, 720 bacteria are placed in a Petri dish. The conditions are such that the number of bacteria is able to dou
MakcuM [25]

Answer:

22.4 hours

Step-by-step explanation:

The population of bacteria is modelled by the equation:

P=P_0e^{rt}

From the the question, the initial population of bacteria is 720.

So after 26 hours, we have:

P=2P_0

This implies that:

2P_0=P_0e^{26r}

2=e^{26r}

26r =  ln(2)

r =  \frac{ ln(2) }{26}

r = 0.0267

We want to find how long it will take for there to be 1310 bacteria present.

1310=720e^{0.0267t}

\frac{1310}{720}  =  {e}^{0.0267t}

\ln(\frac{1310}{720})  = {0.0267t}

0.59853= {0.0267t}  \\ t =  \frac{0.59853}{0.0267}

t = 22.417

To the nearest tenth , it will take 22.4 hours
