By Pythagoras Theorem,
the length of the other leg= (12^2-9^2)^1/2
hope this helps
11-5=6
18-11-7
26-18=8
........... so on and so forth.
I think you get the point.
The answer is 4 and four-fifths.
Well if pi is referred to as 3.14 then the distance around the garden would be 314.
The formula for Circumfrence is pi times diameter, so 3.14 times 100 = 314 (circumfrence)
The answer would be B. You multiply the 2 on both sides, getting 12 on the right. Then you divide by -1, and that switches the sign and makes 12 negative.
