43.The forecast predicted that Dallas County would receive eight inches of rain over the next two days. On Thursday Dallas County received 3.4 inches of rain. On Friday it rained twice with Dallas County Reciving 1.2 inches of rain each time. What was the difference in the actual amount of rain that fell and the amount of rain forecasted?

2.2

44.The circumference of the circular clock in Ms.Rew's room is approximately 36 inches. WHich method can be used to find the radius of the clock?
A.Divide 36 by pi
B.Divide 36 by 2 pi
C.Multiply 36 by pi
D.Multiply 36 by 2 pi
pi=3 for what we're learning right now.

43. Right.

44.
C = pi * d

Which do you think is the answer for 44?

Right.

To find the difference in the actual amount of rain that fell and the amount of rain forecasted, you need to calculate the total amount of rain received and subtract it from the forecasted amount.

On Thursday, Dallas County received 3.4 inches of rain.
On Friday, it rained twice, with each time receiving 1.2 inches of rain. So, the total rain on Friday is 1.2 + 1.2 = 2.4 inches.

To find the total amount of rain received over the two days, you add the rain on Thursday and the rain on Friday:

3.4 + 2.4 = 5.8 inches

Now, you can find the difference by subtracting the total amount of rain received (5.8 inches) from the amount forecasted (8 inches):

8 - 5.8 = 2.2 inches

Therefore, the difference in the actual amount of rain that fell and the amount of rain forecasted is 2.2 inches.

Regarding the second question, to find the radius of the circular clock, you can use the equation C = 2πr, where C is the circumference and r is the radius.

In this case, the circumference of the clock is given as 36 inches.

To find the radius, you need to rearrange the equation:

C = 2πr
Dividing both sides by 2π, we get:
C / (2π) = r

So, to find the radius:
A. Divide 36 by π

Since you mentioned that π is 3 for what you're learning right now, you can divide 36 by 3:

36 / 3 = 12 inches

Therefore, the radius of the clock is 12 inches.
