Come up with 3 real life problems about pi/circle circumference. Please help this is due at 11:59 pm

Some examples of daily uses of Pi:

Electrical engineers used pi to solve problems for electrical applications.

Statisticians use pi to track population dynamics.

Medicine benefits from pi when studying the structure of the eye.

Biochemists see pi when trying to understand the structure/function of DNA.

The circumference of a circle is found using this formula: C=π⋅dorC=2π⋅r.

3+1+4 Fun Facts About Pi Pi is a ratio; as such, it never changes. ... = circumference / diameter. Though pi is irrational (meaning that it can't be expressed by a simple fraction, and the decimal points go on forever without repeating), it is often represented by a rational number: most often 3.14 or 22/7.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
