One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circl

Igoryamba

The area of a circle:
$A=\pi r^2$
r - the radius, which is equal to half the diameter d

The first circle:
$d_1=6 \\
r_1=\frac{6}{2} = 3 \\
A_1=\pi \times 3^2=9\pi$

The second circle:
the second circle has a diameter that is four times the diameter of the first circle.
$d_2=6 \times 4=24 \\
r_2=\frac{24}{2}=12 \\
A_2=\pi \times 12^2 = 144\pi$

The ratio of the area of the smaller cirlce to the area of the larger circle:
$\frac{A_1}{A_2}=\frac{9 \pi}{144 \pi}=\frac{9}{144}=\frac{9 \div 9}{144 \div 9}=\frac{1}{16}$

The ratio is 1:16.

Describe the process for taking a set of data and creating a circle graph from it.

Masja [62]

Answer:

Step-by-step explanation:

A circle chart can be referred to as a pie chart. This is a chart that expresses each fraction of total data in degrees.

The set of data given is summed so as to determine the total value. Then each data in the set is expressed as a ration of the total value, which is multiplied by $360^{o}$ . This is to determine the degree of angles that represent each data in the data set. These angles in degrees can now be used to divide the sum of angles in a circle into wedges.

With each wedge in the circle showing the fractional relationship between each data and the total value in degrees.

Find the area of the shaded polygons

muminat

Answer:

4 square units

Step-by-step explanation:

The vertices of the figure are on grid points, so it is appropriate to use Pick's theorem to find the area.

__

<h3>formula</h3>

Pick's theorem tells you the area is ...

A = i +b/2 -1

where i is the number of grid points interior to the figure (0), and b is the number of grid points on the boundary (10).

<h3>application</h3>

Using the counted values in the formula, we find the area to be ...

A = 0 +10/2 -1 = 4

The area of the polygon is 4 square units.

_____

<em>Additional comment</em>

There are several other ways to find the area. Here are a couple:

<u>decompose the figure</u>

A horizontal line 1 unit up from the bottom will divide the figure into a trapezoid and a triangle. The trapezoid has bases 4 and 1, and height 1, so its area is ...

A = 1/2(b1 +b2)h = 1/2(4 +1)(1) = 5/2

The triangle has base 1 and height 3, so its area is ...

A = 1/2bh = 1/2(1)(3) = 3/2

Then the total area is 5/2 +3/2 = 8/2 = 4 square units.

<u>subtract empty space</u>

The figure occupies a 4×4 square with triangles removed from the left side and the top. Each of those triangles has a base of 4 and a height of 3. The remaining (shaded) area is ...

A = s² -1/2bh -1/2bh

A = 4² -1/2(4)(3) -1/2(4)(3) = 16 -12 = 4 square units
