Solution:
<u>We know that:</u>
- Diameter = 22 meters
- Radius = Diameter/2
- Area of circle = πr²
<u>Finding the radius:</u>
- Radius = Diameter/2
- => Radius = 22/2
- => Radius = 11 meters
<u>Finding the area of the circle:</u>
- Area of circle = πr²
- => Area of circle = (3.14)(11²)
- => Area of circle = 3.14 x 121
- => Area of circle = 379.94 m²
To find a function that represents these values, just substitute x-values in and look for a function that gives you the correct f(x).
A) This works for 0, but not 2
B) This works for 0, 2, and 4 making it the right answer.
