Answer:
7 rpm = 0.73 rad/s
Step-by-step explanation:
R = Radius of merry-go-round = 1.8 m
= Moment of inertia of merry-go-round = 255 kg m²
= Moment of inertia of child
ω = 9 rev/min
m = Mass of child = 24 kg
From the conservation of angular momentum
∴ New angular speed of the merry-go-round is 7 rpm =
Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
<u><em>As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi. </em></u>
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
stands for Area, and
stands for Radius
Now, plug in the given values:
Next, replace 3.14 for pi:
Then, divide both sides by 3.14 ,which gives us:
Please note: 19.15 is rounded
Anyway, to isolate , we take the square root of both sides:
The square root and square on the right side of the equation cancel out, and we are left with:
Please note that 4.38 was rounded
