2) radius = 5 yd find the circumference of each circle

31.42 yards

Step-by-step explanation:

The formula for the circumference is pi multiplied by the diameter.

To work this out you would first multiply 5 by 2, which would be 10 yards. This is because the radius is half of the diameter. Then you would multiply pi by 10, which would be 31.416.

radius= of diameter

Circumference=

1) Multiply 5 by 2.

2) Multiply pi by 10.

3) Round to 2 decimal places.

So, the stock value at the end of December was $349.52

1.) From the table, the change in price in January was a positive $33.88.

Simply add $33.88 to $349.52 (which equals to $383.40)

2.) From the table, the change in price in February was a negative $48.59.

Simply subtract $48.59 from the total (which equals to $334.84)

3.) From the table, the change in price in March was a positive $12.77.

Simply add $12.77 to the previous total (which now equals to $347.58)
