The percent of change can be calculated by finding the difference between the two volumes and then dividing by the original volume.
0.64 - 0.34 = 0.3
0.3/.34 = 0.882
This is approximately an 88.2% increase in volume.
$49.50 × 4 × 5 = $990
$55.25 × 3 × 5 = $828.75
Total earnings = $990 + $828.75
= $1,818.75

This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle. Pythagorean's Theorem will help us find this length.
so
1024 - 100 = y^2 and
y = 30.4 so 30 feet
