Answer:
1) Bigger sector = 168.8pi
1) Smaller sector = 56.3pi
2) Bigger sector = 529.9
3) Smaller sector = 176.6
Step-by-step explanation:
1) Bigger sector = 
×pi×15×15
= 168.75pi
1) Smaller sector = 
×pi×15×15
= 
×pi×15×15
= 56.25pi
2) Bigger sector = ×3.14×15×15
= 529.875
2) Smaller sector = ×3.14×15×15
= ×3.14×15×15
= 176.625

Answer:
v = 12 km/h
Step-by-step explanation:
To find how much she should increase the speed first we need to find the distance traveled:
Where:
d: is the distance traveled =?
v: is the velocity = 8 km/h
t: is the time = 15 min (9:00 to 9:15)
Now, we can find the speed:
Therefore, she should increase the speed to 12 km/h to reach the office at 9:10 am.
I hope it helps you!
