In the figure below, the radius of the larger circle is 6,8 and the radius of the smaller circle is 4.5. Which of the following
Anna [14]

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 = πr^{2}

where r is the <u>radius</u> of the circle and π = \frac{22}{7}

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(6.8)^{2} - π(4.5)^{2}

                                            = π (46.24 - 20.25)

                                            = \frac{22}{7} x 25.99

                                            = \frac{571.78}{7}

<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.

Danielle created a painting using only similar hexagons.
snow_tiger [21]

Answer:

The hexagons have corresponding sides that are proportional

Step-by-step explanation:

Hexagon is a polygon that consists of six sides and six angles.

Two polygons are said to be similar under the following conditions:

1. Corresponding angles of the hexagons are congruent.

2. Corresponding sides of the hexagons are proportional.

As hexagons are similar, the following statement must be true:

The hexagons have corresponding sides that are proportional.

Please Answer this question.
Sergeu [11.5K]

<u>Answer:</u>

The correct answer option is A. \frac{x^{12}}{64}.

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

( 4 x ^ { - 4 } ) ^ { - 3 }

Distributing the power among the terms to get:

4 ^ { - 3 } . 4 ^ { - 4 * - 3 }

4^{-3}.x^{12}

\frac{x^{12}}{4^3}

\frac { x ^ { 1 2 } } { 6 4 }
