In terms of diameter (d), the area (A) of a circle is given by
  A = (π/4)d²
For your larger circle ...
  A = (π/4)*(24 km)²
  A = 144π km² . . . . . . . . area of larger circle

For your smaller circle ...
  A = (π/4)*(8 km)²
  A = 16π km² . . . . . . . . . area of smaller circle


The ratio of the two areas is
  (larger area)/(smaller area) = ((π/4)*(24 km)²) / ((π/4)*(8 km)²)
  = (24/8)² . . . . . . . . . . . . π/4, km cancel, so it simplifies to this
  = 3²
  = 9 . . . . . . this many small circles have the same area as the larger circle

Changing km to ft does not change the ratio of areas.

Which of the following rational functions is graphed below?
Cerrena [4.2K]

Answer:

option B

Step-by-step explanation:

We can see in the graph that the function has two values of x where the value of y goes to infinity: x = -6 and x = 6.

These points where the value of the function goes to infinity usually are roots of the polynomial in the denominator of a fraction (when the values of x tend to these values, the denominator of the fraction tends to 0, so we have a discontinuity in the function).

So the option that represents a function that have these points in x = -6 and x = 6 is the function in option B.

The other options show functions that have only one point that goes to infinity.
