Let's convert the units first.
1.08 kg * (1000 g)/(1 kg) = 1008 g
density = mass/volume
density = 1008 g / 400 cm^3
density = 2.52 g/cm^3
Answer: 2.52 g/cm^3
89 km would be about 55.3 miles! that's the best answer, but if they want you to round then I'd say choose 55 miles
Answer:
17/30
Step-by-step explanation:
Volume of cylinder = πr²h
Volume = π (12)² × 17
= 2448 π units³
Thus the answer is (d)
Answer:
<h2>C.</h2>
Step-by-step explanation:
The equationof a circle:
<em>(h, k)</em><em> - center</em>
<em>r</em><em> - radius</em>
<em />
We have <em>center = (4, -1) → h = 4, k = -1</em>, and <em>r = 9</em>.
Substitute:
