Find the area of a circle with diameter 18 in. Use the value 3.14 for it, and do not round your answer.
Be sure to include the correct unit in your answer.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"

1.5 pounds because you put 9over 6 and then divide by 6
