HELP QUICK !’ ***What is the area of a circle with a diameter of 126 in?
Vladimir79 [104]

Answer:

49,850.64

Step-by-step explanation:

To find the area of a circle, you must use the formula pi r ^2 (pi r squared).

In this case, we are using 3.14 for pi, so we can add that into the formula.

3.1r^2

We also know the radius, so we can add that in too.

3.14 x 126 ^2

Now solve.

126^2 = 15,876

15,876 x 3.14 = 49,850.64

49,850.64 is the answer.

Hope this helped!

Dominick is training for a race. He spends 0.75 hours running each time he runs and 1.5 hours swimming each time
umka2103 [35]

Answer:

The possible graph is "A". A further explanation is given below.

Step-by-step explanation:

The given values are:

Dominick spends on running

= 0.70 hours

He spends on swimming

= 1.5 hours

This week,

Dominick spends more than six hours.

If,

Number of runs be "x".

Number of swimming be "y".

then,

⇒ 0.75x+1.5y>6

⇒ 75x+150y>600

⇒ x+2y>8

Therefore, x+2y=8

x = 0

y = 4

So the above is the correct answer.

Can someone help me with this question please?
Makovka662 [10]

Answer:

  0.15 for each message

Step-by-step explanation:

The charge per message can be found by dividing the charge by the number of messages. Using the first line of the table, we get ...

  charge per message = (total charge)/(number of messages) = $38.40/256

  charge per message = $0.15

Alyssa is charged 0.15 for each text message.

_____

We can check other lines of the table to see if charges are really proportional:

  $26.55/177 = $0.15

  $31.35/209 = $0.15
