Number of earthquakes decreased
Answer- 205 r13
Work: 9853/48, 205 13/48
Answer:
10ft
Step-by-step explanation:
volume= 502ft³
or, πr²h = 502 ft³
or, h= 502/ (4²π)
or, h= 9.98~10ft
Answer:
90°
Step-by-step explanation:
Through point O draw a ray on left side of O which is || to AB & CD and take any point P on it.
Therefore,
∠ABO + ∠BOP = 180° (by interior angle Postulate)
118° + ∠BOP = 180°
∠BOP = 180° - 118°
∠BOP = 62°.... (1)
Since, ∠BOP + ∠POD = ∠BOD
Therefore, 62° + ∠POD = 152°
∠POD = 152° - 62°
∠POD = 90°.....(2)
∠POD + ∠ODC = 180° (by interior angle Postulate)
90° + ∠ODC = 180°
∠ODC = 180° - 90°

Easy. The answer would be 4 1/8.
