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
Answer:
The answer is 1.
Step-by-step explanation:
If it is 5 or more, you round up. If it is 4 or less, you keep it the same.
Answer: 32 apples
Step-by-step explanation:
The ratio of apples to oranges sold is given as 4 to 2. Since Tia wants to sell a total of 48 apples and oranges, the number of apples that she should sell would be:
= 4/(4+2) × 48
= 4/6 × 48
= 32
Therefore, he should sell 32 apples.
