In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
45.5 is your answer, you will have to multiple the height times the base ( 5 x 9.1 )
Answer:
Step-by-step explanation:
1) Initial water level = 30 feet
2) Rate of change = (30 - 25) / (0 - 1) = 5/(-1) = -5
5ft per hour
3) y-intercept = 30
Since each side of a sqare is equal and there are four sides to the square

X being the side length.
Then you would simiply divide by 4 to isolate x

A side length is 56
