Answer:

27.73 square centimeters

Step-by-step explanation:

<em>Assume the shaded region is the area outside the circle but inside the rectangle.</em>

<em />

Now, we need to find the area of rectangle and area of circle. Then we will subtract area of circle from area of rectangle to get our desired answer.

Area of Rectangle = length * width

Area of Rectangle = 8 * 7 = 56

Area of circle is given by the formula:

Area =  \pi r^2

Where r is the radius, which is 3

So,

Area of Circle = \pi r^2 = \pi (3)^2 = 9\pi=28.27

Thus, area of the shaded region is:

Area of Shaded Region = 56 - 28.27 = 27.73 square centimeters

24 red marbles is40% of ? Marbles
Anvisha [2.4K]

Answer: The answer is 60

Step-by-step explanation: 40% = .4 because % means hundredths. So 40% = 40/100 = .4

Let x be the total number of marbles.

Then, .4x = 24

 Divide both sides by .4

         x = 60 and 24 is 40% of 60 marbles

On a map the distance from Fort Collins to Cheyenne is 3.2 inches. The angle formed at Laramie has measure 43.6º, and the angle
MArishka [77]
We can solve this by drawing a triangle with three points. The first point at Fort Collins (F), the second at Cheyenne (C) and the third at Laramie (L).

The angle at F = 46.5, the angle at L = 43.6. We know the side opposite angle L = 3.2 (side FC), now we must solve for the side opposite angle F (side LC).

We can use the law of sines to solve this where:

sinA/a = sinB/b
sin43.6/ 3.2 = sin46.5/LC
LC = 3.2 (sin46.5/sin43.6)
LC = 3.37 inches

We are told 1 in = 10.6 miles, therefore:

3.37 inches x 10.6 miles/in = 36 miles from Laramie to Cheyenne.
