-11y=22/:(-11)
y=-2
x+4*(-2)=-9
x-8=-9
x=-1
I hope this helped.
It would be B, hope i could help out.
What is the question you're trying to ask here?
V=hpir^2
r=10
v=6283
6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches
Answer:
I don't really understand this question
But if it's asking you to switch,
1. r = 2.5
2. r = 12
3. d = 34
