2. In Diagram 2, the diameters of a cylindrical jar and a cylindrical container are 3d cm and d cm respectively. The jar contains water to a depth of 12 cm. The water from the jar is poured equally into 6 empty containers. Calculate the height, in cm, of water level of each container.
Jawab:
Penjelasan dengan langkah-langkah:
diameter of Cylindrical Jar (Cj) = 3d cm
diameter of cylindrical container (Cc) = d cm
Height of Cj = 12 cm
Volume Cj = 6 Volume Cc
H Cc = ?
We need to make equation based on the cylinder's volume
since
V cylinder = πr²h
where radian = 1/2 d
therefore,
Volume Cj = 6 Volume Cc
π.(3d/2)².12 = 6.π.(d/2)².h (eliminate π)
[tex]\frac{9d^2}{4} \times 12= 6 \times \frac{d^2}{4} .h\\[/tex]
[tex]\frac{9d^2}{4} :\frac{d^2}{4} \times \frac{12}{6} =h[/tex]
[tex]\frac{9d^2}{4} \times \frac{4}{d^2} \times 2 = h\\h = 9 \times 2 = 18 cm[/tex]

16. A plumber had two pipes. The ratioof the length of the longer pipe to the shorter pipe was 9 : 2 when he cut 1.65 meter from the longer pipe the remaining length was 3 times that of the shorter pipe. Find the length of the shorter pipe in metres
x = the longer pipe
y = the shorter pipe
x : y = 9 : 2
2x = 9y
x = 9y/2
x - 1,65 = 3y
x = 3y + 1,65
x1 = x2
9y/2 = 3y + 1,65
9y = 2(3y + 1,65)
9y = 6y + 3,3
9y-6y = 3,3
3y = 3,3
y = 3,3/3 = 1,1 m
So the shorter pipe is 1,1 meterlet
x be the length of the longer pipe and
y be the length of the shorter pipe
the given ratio means
[tex] \frac{x}{y} = \frac{9}{2} [/tex]
so,
[tex]x = \frac{9}{2} y[/tex]
when he cut 1.65 meter from the longer pipe the remaining length was 3 times that of the shorter pipe, it means
[tex]x - 1.65 = 3y \\ x = 3y + 1.65[/tex]
substitute x
[tex]x = x \\ \frac{9}{2} y = 3y + 1.65 [/tex]
multiply by 2 we obtain
[tex]9y = 6y + 3.3 \\ 9y - 6y = 3.3 \\ 3y = 3.3 \\ y = 1.1[/tex]
hence, y = 1.1, so the length of the shorter pipe is 1.1 meter

20. In Diagram 2, the diameters of a cylindrical jar and a cylindrical container are 3d cm and d cm respectively. The jar contains water to a depth of 12 cm. The water from the jar is poured equally into 6 empty containers. Calculate the height, in cm, of water level of each container. Use [tex]\pi = \frac{22}{7} [/tex]Jawabanya=18 cm
Jawab:
Penjelasan dengan langkah-langkah:
Cj diameter = 3d
Cc diameter = d
h Cj = 12
V Cj = 6 Cc
therefore
V Cj = 6 V Cc
π (3d/2)².12 = 6 π (d/2)².h
2(9d²/4) = d²/4 h
h = 2 x 9 = 18 cm
