<u>Answer:</u>
The area of one side of a disc is 314 square inches
<u>Explanation:</u>
Given the radius of the disc is 10 inches
The disc is in circular shape and the area of a circle is determined by
A =
, where
A is the area and r is the radius and π = 3.14
Substituting values in the formula,
A = ![3.14 \times(10)^2](https://tex.z-dn.net/?f=3.14%20%5Ctimes%2810%29%5E2)
A =
= 341 sq. inches
Therefore, the area of one side of a disc is 314 square inches

Given
![Ratio = \frac{12}{15}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B12%7D%7B15%7D)
Required
Determine its equivalent proportion
![Ratio = \frac{12}{15}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B12%7D%7B15%7D)
Factorize the given expression
![Ratio = \frac{3 * 4}{3 * 5}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B3%20%2A%204%7D%7B3%20%2A%205%7D)
Divide the numerator and denominator by 3
![Ratio = \frac{4}{5}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B4%7D%7B5%7D)
We apply the same steps to the given options as follows:
1.
![Ratio = \frac{21}{28}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B21%7D%7B28%7D)
Factorize
![Ratio = \frac{7 * 3}{7 * 4}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B7%20%2A%203%7D%7B7%20%2A%204%7D)
Divide the numerator and denominator by 7
![Ratio = \frac{3}{4}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
This is not an equivalent proportion of ![\frac{12}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B15%7D)
2.
![Ratio = \frac{20}{25}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B20%7D%7B25%7D)
Factorize
![Ratio = \frac{5 * 4}{5 * 5}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B5%20%2A%204%7D%7B5%20%2A%205%7D)
Divide the numerator and denominator by 5
![Ratio = \frac{4}{5}](https://tex.z-dn.net/?f=Ratio%20%3D%20%5Cfrac%7B4%7D%7B5%7D)
This is equivalent to
because they both simplify to ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
