Answer:

The radius of the circle is 4 meters.

Thus, 2nd option is correct.

Step-by-step explanation:

Given

Area of a circle = 16π squared meters.

To determine

The radius of the circle = r = ?

Using the formula

Area of circle = πr²

substitute Area of circle = 16π and in the equation

16π = πr²

switch the sides

πr² = 16π

divide both sides by π

πr²/π = 16π / π

r² = 16

r = 4, r = -4

As radiud can not be negative, so

r = 4 meters

Therefore, the radius of the circle is 4 meters.

Thus, 2nd option is correct.

How many quarters make 40 dollars
zzz [600]

Given problem;

  Number of quarters in $40;

   

To solve this problem;

  • <u>Convert the dollar value to cents</u>;  

                 100cents  = $1

               In $40, we would have;  40 x 100 = 4000cents

  • 1 quarter = 25 cents

   So, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;

      Number of quarters = \frac{4000}{25}   = 160

So there are 160 quarters in $40

The Mean Absolute Deviation is commonly known as MAD. The correct statement about the situation is D.

<h3>What is the Mean Absolute Deviation?</h3>

The Mean Absolute Deviation, commonly known as MAD is the average of the difference between the mean and the data points, it can also be referred to as the average of the deviations of the data points from the mean.

Given Two months ago, the mean daily rainfall in a local city was 9.4 cm. The mean absolute deviation was 3.5 cm. Last month, the mean daily rainfall in that city was 11.5 cm, and the mean absolute deviation was 1.6 cm.

As it is known that more MAD for data points means more deviation of the data points from the mean, while it is vice versa if it is less. Therefore, we can conclude Last month, the amount of rain that fell each day varied less than the month before.

Hence, the correct statement about the situation is D.
