Answer 1

Helppppppppppppppppppppppppp

Answer 2

a. thirty-eight point four seven square inches
b. forty-three point nine six square inches
c. eighty-seven point nine two square inches
d. one hundred fifty-three point eight six square inches

Answer 3

Do you have an idea of the answer? Trying to help you, not just give you the answer.

Answer 4

A=πr2
where r is the radius (distance from center to edge, just like a clock hand) and according to your problem statement, you should use π≈3.14 for your calculation.

Answer 5

So. Use A=(3.14)(7)2

Answer 6

he value of \pi has an infinite number of digits, so 78.5 is just the approximate answer, but there are limits to how accurately one can measure and cut wood :-)
