V=pi r^2 h solve for pi please help asap will mark brainliest

kogti [31]

Answer:

$\pi=\frac{v}{hr^2}$

Step-by-step explanation:

So we have:

$v=\pi r^2h$

And we want to solve for π.

First, divide both sides by h:

$\frac{v}{h}=\pi r^2$

Now, divide both sides again by r²:

$\pi=\frac{v}{hr^2}$

And this is our answer :)

Each interior angle of the regular n-gon has a measure of 140

xeze [42]

Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.

Hope this helps :)

Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in th

Cloud [144]

Answer:

Asanji drove for $5$ hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove $= X+3$ hours

Thus, distance travelled by Asanji in $X+3$ hours is equal to distance travelled by Huong in $3$ hours

$45 ( X+3) = 75 (3)\\$

On solving the above equation, we get -

$45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2$

Asanji drove for $3 + 2 = 5$ hours before Huong caught up
