<h2>Answer:</h2>
The equation of the given graph is:
We know that the general equation of a downward parabola with vertex at (h,k) is given by the formula:
where a<0
Here in each of the options we have a= 1 or -1
but as a has to be less than 1 this means that a= -1
Also, we have: (h,k)= (3,1)
i.e. h=3 and k=1
Hence, putting the values of h,k and a in the general equation we get:
Hence, the equation of parabola is:

Answer:
1055.04 cm³
Step-by-step explanation:
Given that,
Height of a cylinder, h = 16 cm
Radius of the cylinder, r = 5 cm
The height of a cone, h' = 12 cm
The radius of a cone, r' = 4 cm
The volume of the cylinder will be :
The volume of a cone is given by :
Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³
Hence, the required answer is equal to 1055.04 cm³.
