<u>Answer:</u>

π inches^{2}

<u>Step-by-step explanation:</u>

We are given a circle with radius 2 inches and one quarter of it as the shaded area and we are to find the area of this shaded region.

For that, we can simply calculate the area of the circle and divide it by 4 since we are to find the area of a quarter.

Area of circle = \pi r^2 = \pi (2)^2 = 4\pi

Area of the shaded region = \frac{4\pi }{4} = π inches^{2}

Ivan

Answer:

8\frac{3}{4} cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4}

= 8\frac{3}{4} cups.

1/10, 3/20, 5/30, 7/40 arithmetic sequence geometric sequence neither
Zina [86]
If a, b, c is an arithmetic sequence then a + c = 2b

a = 1/10; b = 3/20, c = 5/30

a + c = 1/10 + 5/30 = 3/30 + 5/30 = (3+5)/30 = 8/30
2b = 2 · 3/20 = 3/10 = 9/30

8/30 ≠ 9/30

If a, b, c is a geometric sequence then ac = b²

ac = 1/10 · 5/30 = 1/2 · 1/30 = 1/60
b² = (3/20)² = 9/400

1/60 ≠ 9/400
