I think it 10 points for all of it

1. 0.48

2. 0.16

3. 40.98

4. 0.18

5. Because 3 * 9 * 0.01 is 0.27

6. First you have to round the numbers:

3.9 ≈ 4

4.6 ≈ 5

4 * 5 = 20

Step-by-step explanation:

1. 1.6 * 0.3 = 0.48 because 16 * 3 * 0.01 = 0.48

2. 0.8 * 0.2 = 0.16 because 2 * 8 * 0.01 = 0.16

3. 12.8 * 3.2 = 40.98 because 128 * 32 * 0.01 = 40.98

4. 0.03 * 6 = 0.18 because 3 * 6 * 0.01 = 0.18

5. Because 3 * 9 * 0.01 is 0.27

6. First you have to round the numbers:

3.9 ≈ 4

4.6 ≈ 5

4 * 5 = 20

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
