Answer:
31/5
Step-by-step explanation:
[f(4) - f(-1)] / 4-(-1)
Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8
First of all, it's not pie. It's pi.
Now, the problem.
Radius is always 1/2 x d (d meaning diameter)
That gives us 5.
The formula is 3.14 x 5^2(h/3)
If you solve it from left to right, you get 130.83
C I am soooo sorry if I’m wrong
