Arectangular tray has length 60 cm, width 40 cm and depth 2 cm.
it is full of water.
the water is poured into an empty cylinder of diameter 8 cm.
calculate the depth, in cm, of water in the cylinder.
give your answer correct to 3 significant figures.

Step-by-step explanation:

V tray = 60 x 40 x 2 cm ³ = 4800 cm ³

4800 = π r ² h

4800 = 16 π h

h = 4800 / ( 16 π ) cm

h = 95.5 cm is depth of water.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
