The spacing on ladder rungs should never be less than six inches or greater than 12 inches. The majority of 7 foot ladders have between 6 and 10 rungs.
Assuming you mean "foot of the ladder": Sqrt(144 - 81) ie sqrt 63 = 7 feet 11¼ inches. If you mean what you wrote then zero distance!
To find the angle formed between the ladder and the ground, we can use the sine function in trigonometry. The ladder forms a right triangle with the wall, where the length of the ladder is the hypotenuse (7 feet) and the distance from the wall is one leg (4 feet). Using the sine formula, (\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}), we find (\theta = \arcsin\left(\frac{4}{7}\right)). Calculating this gives an angle of approximately 0.588 radians or about 33.69 degrees.

7 foot circumference X 12 inches/foot = 84 inches in circumference
91 inches in 7 foot 7 inches.
The ladder had 25 rungs in total. This can be calculated by adding the 7 rungs walked down to the 15 rungs climbed up, then adding the final 3 rungs. So, 7 + 15 + 3 = 25 rungs on the ladder.

7 on one side and 14 on both sides

The ladder is 7 foot up the wall if the ladder if the ladder is 3 ft away from wall.

There are 12 inches in a foot. Therefore, 7/12 of a foot is equal to 7/12 x 12 = 7 inches.
