Answer:
.
Step-by-step explanation:
Given information:
Radius of circle = 8 cm
Area of sector = 
Formula for area of sector is
where, r is radius and 
is central angle in radian.
Substitute 
and r=8 in the above formula.
Therefore, the measure of the sector in radians is .
Answer:
the answer is 70.84. hope this helps
Step-by-step explanation:
Share 20pounds in the ratio 2:3
Total ratio=2+3=5
2/5×20=8
20-8=12
Sharing 20pounds in that ratio gives 8pounds:12pounds
Share 15cm in the ratio 1:3
Total ratio=1+4=4
¼×15=3.75
15-3.75=11.25
Sharing 15cm in that ratio gives 3.75:11.25
21/10 divided by 2 4/5 represents the time spent on a shift
<h3>How to determine what 21/10 divided by 2 4/5 represent in this situation?</h3>
The given parameters are
Time = 21/10
Shifts = 2 4/5
This means that:
21/10 divided by 2 4/5 represents:
Time/Shift
i.e. time per shift
Hence, 21/10 divided by 2 4/5 represents the time spent on a shift

I am presuming that the question is who won or by how much did the winner win.
distance equals rate times time, or d = r*t
For the Hare d = 1600 and r = 10
1600 = 10 t
Divide both sides by 10
t = 160
The hare finished in 160 seconds
For the tortoise d = 1600 - 780 = 820 (due to the head start) and r = 5.3
820= 5.3 t
Divide both sides by 5.3
t = 154.72 (rounded to the hundredths place)
The tortoise won by 5. 28 seconds (160-154.72)
