A solid cylinder has a radius of 2 cm and a height of 7 cm. It has a density of 3.1 grams
1 answer:
Answer:
Step-by-step explanation:
The first thing you need to do is find the volume.
r = 2cm
h = 7 cm
pi = 3.14
V = pi*r^2 *h
V = 3.14 * 2^2 * 7
V = 3.14 * 4 * 7
V = 87.92 cm^3
Next find the mass using the density formula
Density = mass / volume
Density = 3.1 grams / cm^3
Volume = 87.92 cm^3
3.1 = m / 87.92 Multiply both sides by 87.92
3.1 * 87.92 = m
m = 272.55
Note:
Technically There should be no decimal places. 3.1 is only 2 significant digits. The answer should be 270 grams.
