Answer: 26 feet.
Step-by-step explanation:he
The exercise is not written clearly. Assuming that it asks to find the amount of lumber (in feet) John needs for 3 shelves, let "x" represents that amount of lumber in feet.
Based on the data provided, you know that one shelf requires 
feet of lumber.
You can convert the Mixed number to Decimal number applying these steps:
1. You must divide the numerator of the fraction by the denominator.
2. You must add the result obtained to the Whole number part.
Then you get:
Knowing this, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value. This is:
we know that
volume of the cylinder =
in this problem
Volume=
units³
solve for h
therefore
the answer is
the height of the cylinder is 
Answer:
$20.44
Step-by-step explanation:
first solve for the whole thing
10 x 6 = 60
now to the red part
2 x 1.5 = 3
now the blue
r^2 * pi = a
2^2 * 3.14
4 * 3.14 = 12.56
now add red and blue
3 + 12.56 = 15.56
now subtract that sum from the whole
60 - 15.56 = 44.44
now do
44.44 / 10 = 4.444
now see how much it would cost for the grass
4.444 * 4.60 = 20.4424 ≈ 20.44
it would cost $20.44 to get the grass reseeded
Answer:
20 feet.
Step-by-step explanation:
Pythagoreans theorem states that a^2 + b^2 = c^2
a = 12, squared = 144
b = 16, squared = 256
144 + 256 = 400
√400 = 20
20 feet is the answer.
Hope this helps.
