Answer:
m=-5/8= 0.625 so the slope is 0.625
Step-by-step explanation:
just graph the points in a calculator or like on your phone or any device
Slope=-5/-8 OR 0.625
y2-y1/x2-x1=3-8/-9-(-1)=-5/-8
OR
8-3/-1-(-9)=5/8=0.625
Both ways get the same decimal. I don't know which one you need to use.
Good luck and hope this helps.
r=11 m
Too lazy to explain:
πr²h=v
3.14*r²*12=4560
r²≈121
r is 11 m
