The formula to use is
V = pi*r^2*h

V = volume of cylinder
pi = 3.14 approximately, but we'll leave it as pi
r = radius
h = height

In this problem,
r = 1 since the diameter is 2
h = 4

Plug those two values into the formula
V = pi*r^2*h
V = pi*1^2*4
V = pi*1*4
V = pi*4
V = 4pi

Answer: Choice C

Step-by-step explanation:

(x + 2)² = (x - 1)(x + 14)

x² + 4x + 4 = x² + 13x - 14

-9x = -18

x = 2

Step-by-step explanation:

845/1160 = 0.728

116.5/174 = 0.669

42.25/58 = 0.728

23.4/29 = 0.806

16.9/23.2 = 0.728

25.35/34.8 = 0.728

Hence the 2nd, 4th and 5th options are correct.

Answer: $x^3y^9$

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): Dot was discarded near "7.".

<u>STEP 1: </u>

Simplify $\frac{y^2}{x}$

<u>The equation at the end of step 1:</u>

$((x^4)*\frac{y^2}{x} )*y^7$

<u>Multiplying exponential expressions:</u>

2.1 $y^2$ multiplied by $y^7$ $=y^(2+7)=y^9$

Final result is $x^3y^9$
