i... um.... ok then
Step-by-step explanation:
Answer:
x=1.46497
Step-by-step explanation:
V=(4/3)(pi)(r^3)
A=4(pi)(r^2)
36(pi)=4(pi)(r^2)
36=4(r^2)
9=(r^2)
r=3
V=(4/3)(pi)(3^3)
V=(4/3)(pi)(27)
V=36(pi)
So, in this equation you're just plugging in I'm pretty sure. So x is -2 which is pretty self explanatory.. & y is 2. If you plug them in like so, your answer will turn out to be -6.
6(-2)+3(2)=-6
-12+6=-6
The answer should be -6 not -9.. so that was most likely a typo I'm pretty sure because the answer would not be correct as -9.
