Good question if only because it approximates. I imagine you might have been told to do the question in your head.
Area = pi r^2
r = d/2
r = 4/2
r = 2 feet
pi = 3
Area = 3 * 2 * 2 = 12 square feet <<<<<< Answer.
Somewhere in 1 Kings Ch 7, the Bible makes reference to pi being 3. It's a pretty good estimate considering the number system the Bible used.
B.
(9)^2 + (12)^2 = 225
Square root of 225 gives you 15 !!
We found it by applying Pythagorean’s theorem which only applies to right triangles.
Hope it help !!
Answer: C
Step-by-step explanation:
Since there are 12 inches in 1 foot,
42 feet converts to 42 x 12 = 504 inches. If he makes a cut starting on one side, he will make 504/20 = 25.2 cuts. Since he won't make a partial cut, the answer is 25
Y = 4x -9
y = x-3
Replace the "y" in above equation by x-3
x - 3 = 4x - 9
-3x = -6
x = 2
Then replace x = 2 to the beneth
y = 2 - 3 = -1
I am pretty sure that the answer is
11.61
