Find the diameter of each circle.
Vedmedyk [2.9K]

Answer:

<em>Diameter Length: ( About ) 5.4 km; Option B</em>

Step-by-step explanation:

~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~

1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒

<em>radius = ( About ) 2.7</em>

2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km

<em>Diameter Length: ( About ) 5.4 km</em>

Please help. I've been trying to figure this out for an hour and I still don't understand how it's 72. I feel really stupid beca
rosijanka [135]

Answer:

C. 72\pi

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

\pi r^2=\pi \cdot 24^2=576\pi \ un^2.

The shaded circle is limited by 45° angle, so its area is

\dfrac{45}{360}=\dfrac{1}{8}

of the area of the whole circle.

The area of the shaded circle is

\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.
