Answer:
try 3.14 x 3.14 / 235.5 and that should be your awnser.
Step-by-step explanation:
the equation for diameter is d=2r which is pi times pi divided my the number. if i remeber correctly. lmk if im wrong
The formula of a density is
p = M/V
where p is a density, M is a mass and V is a volume.
Given M = 3.4 kg and V = 2,300 mL or 2,300 cm<span>³, therefore
</span>p = 3.4 kg / 2,300 cm³ = 1.48 x 10⁻³ kg/cm³
5x + 8 = 4
5x = -4
x = -4/5
3(-4/5) = -2.4
Solution: 3x = -2.4
