perimeter of the sector is the sum of the lengths of all its boundaries.thus the perimeter of the sector is L+2r units. θ 360 × 2 π ( r ) + 2 r That would be the length of the arc in the first part and twice the radius in the second part.
Answer:
25
Step-by-step explanation:
GC and BD are 2 intersecting chords thus the measure of the angle formed is
∠DFC = 0.5( m arc CD + m arc BG ), that is
0.5(55 + BG) = 40 ( multiply both sides by 2 )
55 + BG = 80 ( subtract 55 from both sides )
BG = 25
Answer:
99
Step-by-step explanation:
-x-=+
18x6=108
108-6=99
The last graph is the correct answer.
