Answer:
67.5π m²
Step-by-step explanation:
See the diagram given with the question.
The angle moved by the radius line about the center to cover the shaded region is 300°.
As the radius(r) is known to be 9 m.
So, the area of the full circle is πr² = π × (9)² = 81π m².
Now, to cover the whole circle the radius line has to rotate 360° about the center.
Hence, for rotation of 360° the area obtained is 81π m².
Then for rotation of 300° the area obtained will be m². (Answer)

If the <em>width </em>(4) of a <em>rectangle </em>varies inversely as its <em>length </em>(12), the equation that represents the inverse variation is: B.
<em><u>Recall:</u></em>
An inverse proportion relationship is represented with the equation, y = k/x.
k is the constant, which is: k = xy
<em><u>Given:</u></em>
Width varies inversely with the length of a rectangle, if:
width = 4
length = 12
The constant, k = (4)(12)
k = 48
To write the equation that matches the scenario given, plug in the value of k = 48 into y = k/x, which is:
Therefore, if the <em>width </em>(4) of a <em>rectangle </em>varies inversely as its <em>length </em>(12), the equation that represents the inverse variation is: B.
