Answer: 392.7
Step-by-step explanation:
A=πr2=π·52≈78.53982cm² (or 78.54)
78.54 x 5
x + y = 53
x -y = 9 Adding both equations
2x = 62
x = 31 y = 22

hello
so this equation is written in point slope form: 
we can solve for y to get the equation into slope intercept form: y=mx+b
y+1=4/3x
subtract 1 from both sides
y=4/3x-1
slope: 4/3
y-intercept: -1
hope this helps
have a nice day :)
