A measuring cylinder has a mass of 120 g when empty. When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is 160 g. What is the density of the liquid?
1. A measuring cylinder has a mass of 120 g when empty. When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is 160 g. What is the density of the liquid?
Mass of cylinder (empty) = 120 gram
Mass of cylinder (with liquid) = 160 gram
Volume of liquid = 50 cm³
Density of the liquid (ρ) = ?
Answer:
Find the mass of liquid
With liquid - Empty
= 160 gram - 120 gram
= 40 gram
So, the mass of the liquid is 40 gram
Find the density of the liquid
[tex]\rho=\frac{mass}{Volume} \\\rho=\frac{40\ gr}{50\ cm^3} \\\rho=\frac{40}{50}\ gr/cm^3 \\\rho=\frac{4}{5}\ gr/cm^3 \\\boxed{\rho = 0,8\ gr/cm^3}\\or\\\boxed{\rho = 800\ gr/cm^3}\\[/tex]
Hope it helps :)
2. A cylinder has a height of 15cm and a volume of 500cm. Calculate the radius of the cylinder.
Jawaban:
10.6
Penjelasan dengan langkah-langkah:
diketahui:
t = 15 cm
v = 500 cm
ditanya:
r= ?...
rumus:
[tex] {r}^{2} = \frac{v}{\pi.t} [/tex]
[tex] = \frac{500}{3.14 \times 15} [/tex]
[tex] = \frac{500}{47.1} [/tex]
[tex] = 10.6[/tex]
sorry if this answer doesn't help
3. A cylinder has diameter 12cm and height 14cm. A cube has side length y cm. The cylinder and cube have the same volume. Find y
Penjelasan dengan langkah-langkah:
vol cube = vol cylinder
s³ = πr²t
s³ = 22/7. 6.6.14
s³ = 1584
side = y = 12√11 cm

6. 39. A solid cylinder A has a volume of 343 cm cubics.a) Find the volume of another cylinder B which has the same height but the base radius is one-third of the base radius of cylinder A.b) Cylinder B is melted and recast to form cubes of length 2 cm. Find the maximum number of cubes formed.
Jawaban:
a) 38,111 cm²
b) 4
Penjelasan dengan langkah-langkah:
radius A = rA
radius B = rB
a) Volume A = 343 => Volum A = h × π × rA²
maka 343 = h × π × rA²
jika rB = ⅓ rA
maka Volum B = h × π × rB² => h × π × (⅓rA)² => h × π × 1/9 × rA²
343 = h × π × rA²
maka Volum B = h × π × rA² × 1/9 => 343 × 1/9 => 38,111 cm³
b) sisi kubus = 2 maka volumenya = 8 cm³
jumlah maksimal kubus yang terbentuk = 38/8 => 4 buah kubus

8. Q.A cylinder has a diameter of 20 cm and a height of 16 cm. Calculate areathe tube surface!
Jawab:
Penjelasan dengan langkah-langkah:
An area the tube surface = 2πr (r + h)
diameter = 20
r = 20/2 = 10
h = 16
An area the tube surface = 2 (3,14) (10) (10 + 16)
An area the tube surface = 62,8 (26)
An area the tube surface = 1.632,8 cm²
Penjelasan dengan langkah-langkah:
Area Of The Tube surface = 2nr(r + h)Diametre = 20 cmr = D/2 = 20/2 = 10 cmheight = 16 cmMaka,
= 2nr(r + h)
= 2(3,14)(10)(10 + 16)
= 6,28(10)(10 + 16)
= 62,8(26)
= 1.632,8cm^2
