The 9-sided polygon will have a central angle between the vertex and the center of one side of 360°/(2*9) = 20°. Then the apothem is
a = (6 in/2)*cot(20°) ≈ 8.242432 in
The perimeter is 9*6 in = 54 in, so the area is
A = (1/2)Pa = (1/2)*(54 in)*(8.242432 in) ≈ 222.5 in²
Answer:
3.6
Step-by-step explanation:
9-0.2(4-7)^3
9-0.2(-3)^3
9 -0.2 (-27)
9-5.4=3.6
Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
Answer:
249 boxes
Step-by-step explanation:
If you have 5,976 cans and are trying to box them by a certain amount you are basically dividing. So you would divide 5,976 cans by 24 cans per box to get 249 boxes.
Answer:
5192.3 rounded off to nearest ten
Step-by-step explanation:
We get the number:
- 5190
- 3 dropped as a decimal fraction smaller than 1
- 2 dropped and replaced with zero as we round of to ten
- kids missed to replace 2 with zero and lost unit digits by doing that
