This cylinders volume, rounded to the hundredth place, is 452.39 m³

Step-by-step explanation:

volume of cylinder:

→ πr²h

→ π(4)²(9)

→ 144π

→ 452.39 m³ ......rounded to nearest hundredth

  • r=4m
  • g=9m

\\ \tt\hookrightarrow V=\pi r^2h

\\ \tt\hookrightarrow v=\pi 4^2(9)

\\ \tt\hookrightarrow v=16(9)\pi

\\ \tt\hookrightarrow v=144\pi

\\ \tt\hookrightarrow v=144(3.14)

\\ \tt\hookrightarrow v=452.16m^3

Determine whether each statement about the system of the two linear equations is true or false:
Ostrovityanka [42]

Answer:

1 is false

2 is true

3 is false

4 is false

Step-by-step explanation:

y-33=-2

y-33+32=-2+33

y=31

31=3x-2

31+2=3x-2+2

33=3x

33/3=3x/3

11=x

solution is (11,31)

graph of y=-3x-2... y=31 would be a horizontal line on 33 at the y axis
