Pls help (50 points)
svetlana [45]

Answer:

4.5 inches

Step-by-step explanation:

We are given the formula:

V = \pi r^{2}h

Plug in the the radius (3) and volume (127.23):

127.23 = 3.14(3)^{2} h

Square the 3 :

127.23 = 3.14(9)h

Multiply the pi & volume:

127.23 = 28.26h

Divide both sides by 28.26:

127.23 ÷ 28.26 = 28.26h ÷ 28.26

h = 4.5021231...

Mariulka [41]

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

Gradient = \frac{y_ 2 - y_1}{x_2 - x_1}  =  \frac{(10 - 8)}{(4 - 6)}  =  \frac{(2)}{(- 2)} =\boxed{- 1}\\
