Answer:
The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
Step-by-step explanation:
The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

The length of the arc ED is 4x.
Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.

The formula for percentage increase is the increase in the original value. Between last year and this year, there was an increase of 9 science projects, so the increase = 9. The original number of science projects = 43.
9 divided by 43 = 0.2093, about. Multiply it by 100 to get it as a percentage: 20.93%
Since the problem requests it rounded to the nearest tenth, the percent change in the number of projects submitted is 20.9%.
