To get perimeter you add all the sides together. You have 2 sides of 10ft, one side of 8ft and then the half circle. To find the arc length of the half circle you would do 1/2(2πr) which would give you πr. R=4ft since the diameter is 8ft. So you would add 8,10,10 and 4pi. If it wants an exact answer it would be 28+4pi. If it wants an approximate answer it would be 40.6ft
10 days for A by 1,000 m = 2 days 5x2=10 And for B it will be 9.75 kilometers on the thrid day because of .75x3=2.25 then put 7,500 meters to 7.5 kilometers then 7.5+2.25=9.75 kilometers on the third day. For C it would be plan B because it would 20 days to get 20 kilometers for A but plan B is two days ahead of A by taking 7.5x3=22.5=20 days 22.5-.75=21.35 21.35-.75=20.60. Hope this helps because it took me a while.

You multiply 9 all the way back to 1 giving you the answer of 362,880
Answer:
10.5 squared centimetres.
Step-by-step explanation:
First, find the area of that sector. We are already given that the circle is 154 squared centimetres.
We are given 90 degrees (or one fourth of the circle). Thus, divide 154 by 4 to get the area of the sector (the white area).
The area of the sector is 154/4 or 38.5
We then need to find the area of the square. After that, we can subtract the sector area (the white area) from the area of the square (the total area) to find the area of the shaded section.
The area of the square is 7*7 or 49.
Thus, the shaded portion will be 49-38.5 or 10.5 squared centimetres.
