Answer: 3
Step-by-step explanation:
Let say x the width of the tank,
x+4 its length,
x+2 its height
<u>width=3</u>
length=3+4=7
height=3+2=5
If the inscribed square has sides of 8in, the diameter of the circle is equal to the diagonal of the square.
d^2=x^2+x^2
d^2=2x^2
d=√(2x^2)
Since d=2r, r=d/2 so
r=(1/2)√(2x^2)
r=√((2x^2)/4)
r=√(x^2/2), since x=8
r=√(64/2)
r=√32
r=√(16*2)
r=4√2 in (exact)
r≈5.66 in (to nearest hundredth of an inch)

Answer:
<em>713,900</em>
Step-by-step explanation:
713,<u><em>9</em></u>49
The bold, italic, underlined digit is the hundreds digit.
To round to the nearest hundred, change all digits to the right of the hundreds digit to 0. Now you have
713,900
There is one more step. Look at the first digit that used to be to the right of the hundreds digit. If it is from 1 to 4, the hundreds digit remains the same. If it is from 5 to 9, the hundreds digit goes up by 1. In this case, the first digit to the right of the hundreds digit was 4, so the hundreds digit does not go up by 1.
Answer: 713,900
