r = 3 + 3cos(θ) polar equation would best match the desired audible range of the microphone.

<h3>How do you know if an equation is polar?</h3>
  • Determine the kind of polar equation.
  • The polar equation has the shape of a limaçon, and is written as r = a - b cos.
  • We just need to assess the equation throughout the range [0, 1] and then reflect the graph about the polar axis because the equation passes the condition for symmetry to the polar axis.

<h3>What is a polar in math?</h3>
  • The polar coordinate system in mathematics is a two-dimensional coordinate system in which the distance from a reference point and the angle from a reference direction are used to identify each point's location on a plane.

<h3>What is the meaning of polar form?</h3>
  • In addition to the rectangular form, a complex number can also be represented in polar form.
  • Typically, we write complex numbers as z = x + iy, where I is an imaginary integer.
  • However, in polar form, complex numbers are modeled as a union of argument and modulus.

What Is the area of the shaded part???​
Aloiza [94]

Answer: The area of the shaded region is 27.74 centimeters squared

Step-by-step explanation: The diagram shows a two-in-one figure, a circle inscribed in a rectangle. The shaded region is the part of the rectangle not covered by the circle, hence we would have to subtract the area of the circle from that of the rectangle.

Area of Rectangle = L x W

Area of rectangle = 8 x 7

Area of rectangle = 56

Also,

Area of circle = Pi x r^2

Area of circle = 3.14 x 3^2

Area of circle = 3.14 x 9

Area of circle = 28.26

Area of shaded region is given as area of rectangle minus area of circle

Therefore, shaded region = 56 - 28.26

Area of shaded region = 27.74 centimeters squared
