Option D is correct.
Step-by-step explanation:
We are given:

We need to find a in terms of b and c
We have: 
Put value of d 

So, value of a in terms of b and c is: 
Option D is correct.

An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
<u>Answer:</u>
zero
<u>Explanation:</u>
<u>In any system:</u>
the ground (base) is referred to as zero lever
what comes above the ground level would be positive
what comes below the ground level would be negative
<u>Now, we are given that:</u>
she lives on the ground floor.
Based on the above, the representation would simply be zero
