I am not sure what the answer is but covert them into a decimal and then divide it
Answer:
here,x=123, is the answer.
Answer:
13yd
Step-by-step explanation:
Perimeter is all the side lengths added
A <em>circle</em> is a figure <u>bounded</u> by a <em>curved</em> side which is referred to as <em>circumference</em>. Thus the area of the <u>shaded</u> region is option D. 81.65.
A <em>circle</em> is a figure<u> bounded</u> by a <em>curved</em> side which is referred to as <u>circumference</u>. Some of its <u>parts</u> are radius, diameter, sector, arc, etc.
The area of a <u>circle</u> can be determined by the given <em>expression:</em>
Area = π![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
where r is the <u>radius</u> of the circle and π = ![\frac{22}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B7%7D)
So, the area of the <u>shaded</u> region can be determined as:
Area of the <em>shaded</em> region = <em>area </em>of the <u>larger</u> circle - <em>area</em> of the <u>smaller</u> circle
Area of the<em> shaded </em>region = π
- π![(4.5)^{2}](https://tex.z-dn.net/?f=%284.5%29%5E%7B2%7D)
= π (46.24 - 20.25)
=
x 25.99
= ![\frac{571.78}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B571.78%7D%7B7%7D)
<u>Area</u> of the <em>shaded</em> region = 81.683
Thus the<u> appropriate</u> answer to the question is option D. 81.65.
