What is the circumference and area of a circle with a radius of 4 meters? round your answer to the nearest tenth. (use 3.14 for pi.)

Circumference = 25.1 meters.

Area = 50.2 square meter.

Step-by-step explanation:

The circumference of a circle is given by :-

Area of circle is given by :-

, where r is the radius.

Given : Radius = 4 meters

Then circumference of the circle will be :-

Area of circle is given by :-

\

Circumference = 2(pi)r
C = 2(3.14)4.0= 25.12 round 25.10 m

The sample space of events that represent the picking out of letters at two draw without replacing is:

     {T-I, T-M, T-E, I-T, I-M, I-E, E-T, E-M, E-I, M-I, M-T, M-E}

Step-by-step explanation:

Since, there are four choice of drawing a first tile:

             T     I     M     E

and now:

If first tile is drawn as T then the outcome corresponding to T on second draw are:

                        T-I    T-M     T-E

(T-T is not possible since there is no replacement of first tile )

Similarly if I is drawn on first draw then the outcome corresponding to I in second draw is:

                      I-T     I-M     I-E

(I-I is not possible since there is no replacement of first tile )

If M is drawn on first draw then the outcome corresponding to M in second draw is:

                     M-T     M-I    M-E

(M-M is not possible since there is no replacement of first tile )

Now if E is drawn on first draw then the outcome corresponding to E in second draw is:

                         E-T     E-I      E-M    

(E-E is not possible since there is no replacement of first tile )

Hence, total outcomes are:

      {T-I, T-M, T-E, I-T, I-M, I-E, E-T, E-M, E-I, M-I, M-T, M-E}
