Originally, the diameter was 110 m, so the radius was 55 m. To get the area, you square the radius and multiply by π. That's 55^2 * π, making the original area 3025π m^2.
After, the diameter decreased to 107 m, making the radius 53.5 m. Again, you square the radius and multiply by π, making the new area 2862.25π m^2.
Subtract the 2862.25π from 3025π, giving you a total reduction of 162.75π square meters.
Rounded to the nearest hundredth, that's 511.29 square meters.
Answer:
(-1,-4)
Step-by-step explanation:
6m-5n=14 equation 1
2m+2n= -10 equation 2
using equation 2 we have
2m=-10-2n
m=-5-n equation 3
using equation 1 we have
6*(-5-n)-5n=14
-30-6n-5n=14
-11n=14+30
-11n=44
n=-44/11
n=-4
using equation 3
m=-5-n
m=-5-(-4)
m=-1
finally we have
(-1,-4)
Hello There!
Statistics is a tool used to help people process, summarize, analyze and interpret data for making better decisions.
It helps us with future events if we know what has happened in past.
Helps us make better decisions.
The better we know about the future of an outcome, the more possibility we have to work around it.
