Answer:
3,3
Step-by-step explanation:
20096m.
Since the radius is 80, the formula is x²×3.14.
80²=6400
6400×3.14=20096
m is the unit
Answer: 20096 meters
Answer:
<h3>AB ≈ 70m</h3>
Step-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
The solution will be x>1/6
Answer:
x = 15
Step-by-step explanation:
2 = -7/4 + 1/4x
+7/4 +7/4 Add 7/4 to both sides
15/4 = 1/4x Divide both sides by 1/4
15 = x
