Rounding with thousands
Help would be appreciated

1: 35,620 -> 35,600 -> 36,000 -> 40,000

2: 54,390 -> 54,400-> 54,000 -> 50,000

3: 159,100 -> 160,000 -> 200,000

4: 90,890 -> 90,900 -> 91,000 -> 90,000

5: 39,739 -> 39,740 -> 40,000

6: 9,650 -> 9,600 -> 10,000

7: 12,450 -> 12,500 -> 13,000 -> 10,000

Step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

i'm not sure how to show the work for this

answer : c and d or 4(29 + 6)

4(29) + 4(6)
