Answer:
radians
Step-by-step explanation:
Arc length and radius is given. So, we need to know the arc length formula for a circle.
That is:
Where s is the arc length
r is the radius
is the angle (IN RADIANS)
We have:
s = 15.5
r = 9
Now, we substitute and find the angle:
The angle, in radians, in 1.72
Answer:
First Place wins in 15 events
Second Place wins in 12 events
Step-by-step explanation:
Let
the number of events winning first place be "f"
the number of events winning second place be "s"
Total 27 swimming events, we can write:
First place wins is THREE MORE than 2nd place wins, so we can write:
Replacing 2nd equation in 1st equation, we can solve for "s":
We know
f = s + 3
so,
f = 12 + 3
f = 15
Thus,
<u>First Place wins in 15 events</u>
<u>Second Place wins in 12 events</u>
