Answer:
Step-by-step explanation:
Area:
π
π *Square 2x*
π *Divide by π*
*Divide by 4*
*Square root*
*Solve*
x ≈ 3.482
Now take the same equation but replace 2x with 3x
π
Now replace x with 3.482 and solve for area.
Volume:
π *Insert variables*
π *Cube 2x*
π *Multiply on both sides*
π *Divide by π*
*Divide by 8*
*Cube root*
*Solve*
x ≈ 2.208
Now take the same equation but replace 2x with 3x
π
Now replace x with 2.208 and solve for volume.

Answer:
r = 1
Step-by-step explanation:
Use the distributive property to multiply −6 by −3+5r.
18−30r=−5−7r
Add 7r to both sides.
18−30r+7r=−5
Add −30r and 7r to get −23r.
18−23r=−5
Subtract 18 from both sides.
−23r=−5−18
Subtract 18 from −5 to get −23.
−23r=−23
Divide both sides by −23.
r=−23/−23
Divide −23 by −23 to get 1.
r=1
Answer:
y=− x^2 /4-4
Step-by-step explanation:
<span>w = 0.4444444444x
becase you gotta divide each side by 9 so if you simplify it its
</span><span>w = 0.4444444444x</span>
