Answer:
s = 4.28 cm (Answer A)
Step-by-step explanation:
1) The formula for the circumference of a circle of radius r is C = 2(pi)r, and this corresponds to a full circle, with central angle 360 degrees.
2) Here the circumference is 28 cm. Therefore, solving for the radius involves the following calculation: 28 cm = 2(pi)r, or
r = (28 cm) / (2 pi), or (28 cm) / 6.28 = 4.46 cm.
3) The arc length s = r(theta), when the central angle (theta) is 55 degrees, is (55/360) times the circumference of the circle: (55/360)(28 cm), or
s = 4.28 cm (Answer A)
Answer:
B. I and III
Step-by-step explanation:
I and III both have the same data:
March, 73
April 74
May 78
June 84
July 75
II has different data
March 71
April 72
May 85
June 90
July 60
Since I and III have the exact same data, choice B is the best answer
Hope this helps! :)
Answer:
25 remainder of 4
Step-by-step explanation:
Answer:
And then we can find the distance travelled in 11 hours with this formula:
And replacing we got:
So then after 11 hours she will travel 668.8 mi
Step-by-step explanation:
For this case w eknow that Alicia drove at a constant speed 182.4 mi in 3 hours. We can find the speed with this formula:
Where V is the velocity, D the distance and t the time if we replace we got:
And then we can find the distance travelled in 11 hours with this formula:
And replacing we got:
So then after 11 hours she will travel 668.8 mi
