Answer:
There is 120 milligrams of caffeine in a cup of coffee.
Step-by-step explanation:
A cup of brewed tea has 54 milligrams less caffeine than a cup of brewed coffee. A cup of tea has 66 milligrams of caffeine.
Let the amount of caffeine in a cup of coffee be = x
In the equation form, we can denote this as:
Solving for x
x = 120
Therefore, there is 120 milligrams of caffeine in a cup of coffee.

The moment of inertia about the y-axis of the thin semicircular region of constant density is given below.
Any item that can be turned has rotational inertia as a quality. It's a scalar value that indicates how complex it is to adjust an object's rotational velocity around a certain axis.
Then the moment of inertia about the y-axis of the thin semicircular region of constant density will be
x = r cos θ
y = r sin θ
dA = r dr dθ
Then the moment of inertia about the x-axis will be
On integration, we have
Then the moment of inertia about the y-axis will be
On integration, we have
Then the moment of inertia about O will be
