Answer: radius = 10 cm.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π r² h
Where:
r = radius
h = height
Replacing with the values given:
3768 =π r² 12
Solving for r
3768/ (12π) = r²
99.95 = r²
√99.95 = r
r = 9.99 ≅ 10 cm (rounded)

Answer:
y = 3/5x + 12/5
Step-by-step explanation:
y = mx + c
0 = 3/5 ( -4 ) + c
0 = -12/5 + c
12/5 = c
y = 3/5x + 12/5
Answer:
∡x = 20°
∡y = 160°
∠z = 160°
Step-by-step explanation:
Angles on a straight line sum to 180°
⇒ ∠z + 20° = 180°
⇒ ∠z = 180° - 20°
⇒ ∠z = 160°
The central angle measure equals the corresponding arc measure.
⇒ ∡x = 20°
⇒ ∡y = ∠z = 160°
