Answers
The polar form of the equation x² + y² = 16 is x = 4 or y = 4 or r = 4 ( x = y = r = 4) option (B) is correct.
What is the polar equation?
A polar coordinate system is a two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane.
It is given that:
The rectangular form of an equation is:
x² + y² = 16
The above equation representing a circle equation:
We can write the above equation as follows:
x² + y² = 4²
As we know, the polar form of the equation is:
x = r cos(θ)
y = r sin(θ)
r is the radius of the circle
r = 4
θ is the angle made by the component of x and y:
tanθ = y/x
tanθ = r/r; x = y = r
tanθ = 1
θ = 45 degrees
Thus, the polar form of the equation x² + y² = 16 is x = 4 or y = 4 or r = 4 ( x = y = r = 4) option (B) is correct.

Answer:
32 cubic inches of air are needed to fill it completely.
Step-by-step explanation:
A basketball has the format of a sphere.
The volume of a sphere with radius r is given by the following equation:
In this question:
Radius of 4.5 inches. So the volume, in cubic inches, is:
The volume of the ball is 382 cubic inches.
350 cubic inches have already been filled.
So 382-350 = 32 cubic inches of air are needed to fill it completely.
