Circumference = 2 pi r , so
36 pi = 2 pi r
r = 36 pi / 2 pi
= 18 cm answer
Answer:
Explanation:
The proportions of dimes and nickels in the withdrawls recorded by the student are:
- dimes: 12/25
- nickels: 13/25
Thus, the best prediction of the total number of dimes in the bag is found using the same ratio of dimes:
- dimes in the bag = (12/25) × 200 = 96 ← answer
Answer to 4.
About 106.66
If they ask if a rounded answer it would be 107. You just divide 2560 by 24 because you know 24 balls is 3 pounds.
Dakota would have 52 boxes after 4 hours and Alice would have 52 boxes with a total of 104 boxes
If the co-vertices are (0, 3) and (0, -3) where x is 0 and y has a value, then y is the minor axis. That means that the x axis is the major axis. Because of what the co-vertices are, the center of the ellipse is at the origin. The formula for an ellipse that has a horizontal major axis is

. The a value will always be larger than the b value, therefore, the a value goes under the coordinate that is the major axis. Here, its the x-axis. a is the distance that the outer edge of the ellipse is from the center. It's 8 units away from the center along the x axis and 3 units along the y axis from the center. So a = 8 and a^2 = 64; b = 3 and b^2 = 9. Our formula then is
