C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...

Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r  ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi 
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!

Function f is shown below <br> f(-3) <br> f(4)<br> find x when f(x) = 5<br> find x when f(x)= -3
hjlf

Answer:

See below ~

Step-by-step explanation:

Based on the graph,

  1. <u>f(-3)</u>
  • f(-3) = 0

   2. <u>f(4)</u>

  • f(4) = -3

   3. <u>x when f(x) = 5</u>

  • f(x) = 5
  • x = 0

   4. <u>x when f(x) = -3</u>

  • f(x) = -3
  • x = ±4
