We use direct proportionality:

360⁰......Pi×R² (full circle)

120⁰.......x

x=120×pi×R²/360=pi×R²/3

x=pi×4²/3=16.76mi²

A=3×pi cm², for an angle of 2×pi/3=120⁰

In a similar way we compute the area of the full circle:

360.........x

120..........3×pi

x=3×pi×360/120=9×pi=3²×pi.

Thus the radius is 3cm.

Find angle &lt;QPS in the diagram​
marin [14]

Answer:

40°

Step-by-step explanation:

Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.

40 POINTS Geometry homework
kicyunya [14]

\angle{DBC   }=(5x+4)°

\angle{ A  }=(2x-2)°

\angle{C   }=(4x-6)°

we know that,

\angle{DBC}=\angle{A}+\angle{C}

According to the question,

\tt{ 5x+4=2x-2+4x-6  }

\tt{ 5x+4=6x-8  }

\tt{ 6x-5x=4+8  }

\blue{x=12   }

so,

\angle{C }=(4x-6)°=(4×12-6)°=(48-6)°=42°
