Answer:
8 feet.
Step-by-step explanation:
The formula for volume of a cylinder is (using 3.14 for
). So it would be
times 7 times 3.14 which equals
times 21.98. 1406.72 divided by 21.98 is 64. The square root of 64 is 8. The radius is 8.

<u>Answer:</u>
The correct answer option is A. 18.
<u>Step-by-step explanation:</u>
We have a right angled triangle with the complete values of two sides: the perpendicular and the base with side lengths 40 and 30 respectively.
We can use the Pythagoras Theorem to find the hypotenuse.
Assuming the hypotenuse to be A:
To find x, we will subtract 32 from the length of hypotenuse:
Therefore, the value of x = 18.

Answer:
1, 5, 2, 4, 3, 7, 6
Step-by-step explanation:
After dividing by the leading coefficient, each equation can be put into the form ...
x² + y² + ax +by +c = 0
Subtracting c and separately completing the square for x-terms and y-terms, we get ...
x² + ax + (a/2)² + y² + by + (b/2)² = -c + (a/2)² + (b/2)²
(x +a/2)² + (y +b/2)² = r² = (a/2)² + (b/2)² -c . . . . . rewrite in standard form
Ordering by the square of the radius length will match the ordering by radius length, so we just need to compute (a/2)² +(b/2)² -c for each given equation. I find it convenient to let a calculator or spreadsheet do this calculation (see attached).
In the order the equations are given, the square of the radius is ...
3, 18, 45, 23, 5, 117, 46
So the order of the equations from smallest radius to largest is ...
1, 5, 2, 4, 3, 7, 6
