Answer:

4/3π - √3

Step-by-step explanation:

Pie piece of circle is area of circle x portion of circle

πr²*x/360 = π(2)²*120/360 = 4/3π

Then you must subract the non-right triangle area

1/2ab sin C = 1/2(2)(2) sin 120 = 2 * √3/2 = √3

4/3π - √3

AleksandrR [38]

Step-by-step explanation:

length \: between \: ( - 2, - 1) \: and \: (6,4) \\  =  \sqrt{(x _{1} - x  _{2} )² + (y _{1}  - y _{2})²  }  \\  =  \sqrt{( -  2 - 6)²+ ( - 1 - 4)²}  \\  =   \sqrt{64 + 25}  \\  =  \sqrt{100}  \\  = 10 \: units \\ radius = 10 \: units \\ diameter = 2 \times radius \\ d = 2 \times 10 \\ d = 20 \: units

A map of a park says its scale is 1 to 100. What does that mean?
Alex777 [14]

A scale is a term that refers to the <em>representative fraction</em> for comparing the <u>original</u> length and <u>image</u> length of a given <u>object</u>. It means implies that every 1 unit on the <u>drawing</u> is equal to <u>100</u> units on the <u>park</u>.

A <em>scale</em> is a term that can be referred to as the <em>representative fraction</em> that compares the <u>original</u> length and <u>image</u> length of a given <em>object</em>. Types of <u>scale</u> include enlarged scale, reduced scale, and real scale.

  • Enlarged scale is a <u>scale</u> that is used when the <u>size</u> of a given <em>object</em> is to be <em>increased</em>.
  • <em>Reduced scale</em> is used when the <u>size</u> of a given <u>object</u> is to be <em>decreased</em>.
  • <u>Real scale</u> implies the <em>exact size</em> of a given <u>object</u>.

<u>Scale</u> can be expressed as;

Scale = \frac{length on drawing}{original length}

Thus a <em>scale</em> has no unit.

Therefore, the given question <em>implies</em> that every 1 unit on the <u>drawing</u> is equal to 100 units on the <u>original</u> park. Thus it is a <em>reduced scale</em>.
