Pie goes on forever, so you round it to 3.14.           
3.14*2= 6.28
Hope that helped!

Pie is a infinite number. Most times you just use 3.142 as pie. So you do 3.142x2. But i recommend you using a calculator and pressing the pie button. It will give you a lot accurate answer...

What is x? I will give brainliest if you explain your answer.
horsena [70]

Answer:

  • x =  {0, π/2, 3π/2, 2π}

Step-by-step explanation:

  • cotx cos x - cot x = 0
  • cotx( cosx - 1) = 0

1. <u>cotx = 0</u>

  • x = π/2 + πn
  • In the interval [0, 2π] we have π/2 and 3π/2

2. <u>cosx = 1</u>

  • x  = 0 + 2πn
  • In the given interval we have 0 and 2π

<u>So the solution set is:</u>

  • x =  {0, π/2, 3π/2, 2π}

30 POINTS IF U CAN HELP PLEASE. in the figure below, a tangent and a secant are drawn to a circle from the exterior point E. Sup
dimulka [17.4K]

Answer:

19.5  = CD

Step-by-step explanation:

The square of the tangent = the the whole secant times the outside part of the secant.

EG²= (ED)(EC)

13² = (26)(EC)

169 = 26EC

169/26 = EC

 6.5 + EC

Now  ED = EC + CD

         26 = 6.5 + CD

        26 - 6.5 = CD

           19.5  = CD
