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>

ABCD is a Rhombus with side length 10 cm. Angle ADC = 40. DAC is a sector of a circle with center D. BAC is a sector of a circle

The value of the <em>shaded</em> area is approximately 34.907 square centimeters.

<h3>How to calculate the area between a rhombus and a circle</h3>

According to the description in statement we prepared a representation of the figure in the image attached below. The <em>shaded</em> area is equal to the area of the <em>circle</em> sector ( $A$ ), in square centimeters:

$A = \frac{\theta\cdot \pi \cdot R^{2}}{360}$ (1)

Where:

$R$ - Length of the radius, in centimeters.
$\theta$ - Angle of circle arc, in degrees.

If we know that $\theta = 40^{\circ}$ and $R = 10\,cm$ , then the area of the circle is:

$A = \frac{(40)\cdot \pi\cdot (10\,cm)^{2}}{360}$

$A\approx 34.907\,cm^{2}$

The value of the <em>shaded</em> area is approximately 34.907 square centimeters. $\blacksquare$
