Answer:
The correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by
Option D is correct option.
Step-by-step explanation:
The circumference of table top = 24
inches
We need to find area of table top
The formula used to find area is: 
We need to find radius of tabletop.
The formula used to find circumference is: 
Putting value of circumference we can find radius

So, radius of table top = 12
Now, finding the area:

So, the correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by
Option D is correct option.
32/80 so divide that by 5 = 6.4/20 then multipy that by 100/1 so the answer is 640
0.475
1000 milliliters is equal to 1 liter
2 hours = 120 minutes
5/6 of an hour = (60/6)X5 = 50 minutes
1 tour = 120+50 = 170 minutes
170X9 = 1530 minutes = 25.5 hours
Therefore, they spent 1530 minutes or 25.5 hours on the tour.
