G=37
Angle ACD and angle DCB are a linear pair. Meaning they are supplementary.
ACD=90 degrees
180-90=90
90 degrees equals the angle of DCB.
90-53=37
So g=37
Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm
