Equation: (1 2/3)(2 1/3) = x
Answer: 3 8/9 cups
Step-by-step explanation:
x represents the amount of flour she will need in cups.
To solve, convert the mixed numbers to improper fractions and multiply...
1 2/3 becomes 5/3
2 1/3 becomes 7/3
Now we have
(5/3)(7/3) = x
35/9 = x
35/9 is 3 8/9 as a mixed number
In cubic feet, the volume of the rod is given by the formula for the volume of a cylinder.
.. V = (π/4)*d^2*h
.. = (π/4)*(1/12 ft)^2*(12 ft)
.. = π/48 ft^3
Then the weight is
.. (490 lb/ft^3)*(π/48 ft^3) ≈ 32 lb
6.28125
Just divide 9 by 32 then add 6
