The volume of a cylinder is

V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:

V=40(3.14)(10^2)

V=12560 ft^3

The weight of Lyle’s dog increased from 29.7 pounds to 48.9 pounds in an 8-month period. What was the dog’s average weight incre

krok68 [10]

First subtract the weight the dog weighs now to the weight he was:

48.9
- 29.7
------------
19.2

Then take the number you got which is the weight the dog gain in total, and divide it by the months the dog gained weight to get the average weight gained each month:

19.2/8 = 2.4

The average weight gain each month was 2.4 pounds.

Hope this helped you!

Please solve this question asap

Step-by-step explanation:

$y = \sqrt{4x + 6}$

${y}^{2} = 4x + 6$

${y}^{2} - 6 = 4x$

$\frac{1}{4} ( {y}^{2} - 6) = x$

Swap x and y

$\frac{ {x}^{2} - 6 }{4} = y$

Are the following lines parallel, perpendicular, or neither? y= -4/3x - 5 and y= 3/4x - 5

san4es73 [151]

Perpendicular is the answer because for it to be perpendicular it has to be the opposite 3/4’s opposite is -4/3 which is why the answer is perpendicular

Hi there! :)

Answer:

x = -2

Step-by-step explanation:

5 - 3x = 11

Subtract "5" from each side of the equation → 11 - 5 = 6

-3x = 6

Divide each side of the equation by "-3" → 6 ÷ -3 = -2

x = -2

There you go! I really hope this helped, if there's anything just let me know! :)
