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:
A-8
Step-by-step explanation:
Any other higher number plugged in makes the equation false
Answer:
Answer:
x=−24
Step-by-step explanation:
the only variable is x and -24 is the value of this variable

Since it's a Trapezoid with its non - parallel sides equal to one another,

[ By forming co - interior angle pair ]



Now, similarly,



Similarly,
