The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
Answer:5(5x-1)
Step-by-step explanation: for a product the equation above
25x-5
Since 5 is divisible by 25
25/5=5
5/5=1
5(5x-1)
0.3% is the answer because the decimal is over one meaning the percent is over 100
Each bicycle gives a profit of around 60 dollars.
2400/60= 40
The store must sell around 40 bicycles every month.
