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:
Step-by-step explanation:
<h3>Given</h3>
- Θ= 168°
- t = 0.28 sec
- r = 3 mm
<h3>To find </h3>
<h3>Solution</h3>
<em>Formula for linear velocity</em>
<u>Converting the angle measure from degrees to radians</u>
- 168° = 168*π/180 = 168*3.14/180 = 2.93
<u>Substituting values</u>
- v = 2.93*3/0.28 mm/sec =
- 31.39 mm/sec =
- 0.03 m/sec rounded to nearest hundredths
24 is the correct answer your right
Each half-life reduces a sample by one half.
So after 1 half-life there is 1/2 left
2 half-lives 1/4
3 half-lives 1/8
4 half-lives 1/16
5 half-lives 1/32
There would be (1/32) of 120 remaining.
or 3.75 grams.
