Answer:
6:1
Step-by-step explanation:
48:( 4+4 )
= 48:8
= 6:1
r = 4
θ = 16
θ = 4
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.
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.

Step-by-step explanation:
Answer:
8(x-10)
Step-by-step explanation:
When the calculation is repetitive, I like to let a calculator or spreadsheet do it. The value of the given function is
4·20 -10 = 70
Only the expression 8(x-10) = 8(20-10) = 80 has a larger value for x=20.

Answer:
≈ 201
Step-by-step explanation:
V= πr²h/3
V= 3.14*4²*12/3= 200.96 ≈ 201
The volume of the cone is 201.06 units³.
The volume of a cone is given by the formula:
Volume = (1/3) * π * r² * h
where r is the radius of the base and h is the height of the cone.
In this case, r = 4 units and h = 12 units. Using 3.14 for π, we can calculate the volume of the cone as follows:
Volume = (1/3) * 3.14 * 4² * 12
Volume = 201.06 units³
Therefore, the volume of the cone is 201.06 units³.
