The circumference C of the circle is
Answer:
d=1.4
Step-by-step explanation:
cuz 10-1.4=8.6
For this problem you can do it one of two ways. The first way would be simply take the square root because the area of a square is one side squared. The other way using the same rule would be to go up from a reasonable number and square it, if that is not the number you are looking for add 1 to the original number and square it again. if you cannot square and square root in your head, you should be allowed to use a calculator to get the answer or 17 as the length of a side.
0 = x because 0 + 5 = 5 plus 2 = 7
8/9 / 4/9
=(8/9)*(9/4) Multiply by second reciprocal
=(2/1)*(1/1) Cross reduce
=2 Multiply
