Circumference = 2 pi r
11304 = 2 x 22/7 x r
11304 x 7/2x22 =r = 1798.36
Answer: C
I can’t explain it very well, but the answer is C
The shortcut is the hypotenuse of a right triangle with legs 6 and 8, so 6²+8²=c²
36+64=c
100=c²
c=10.
so he traveled 6+8+10=24km
I hope it helps you get it right
You are adding s^2 to your 128 ft^2. s^2 is a common representation of a square. So you could think of it as adding an area of a square of side "s" to your deck.
So one way of drawing it is to draw a rectangle with area 128 ft^2 and attaching a square to one of its side. The square that is attached has a side lenght of "s."
