Answer:
170 N
Explanation:
The weight of an object is equal to its mass times the acceleration due to gravity. The object's mass is equal to its density times its volume. Volume of a cylinder is equal to pi times the square of the radius times the height.
Relevant equations are:
W = mg
m = ρV
V = πr²h
where W is the weight,
m is the mass,
ρ is the density,
V is the volume,
r is the radius,
and h is the height.
Converting centimeters to meters, the volume of the cylinder is:
V = π (0.10 m)² (0.20 m)
V = 0.00628 m³
The mass of the cylinder is:
m = (2700 kg/m³) (0.00628 m³)
m = 17.0 kg
The weight of the cylinder is:
W = (17.0 kg) (10 N/kg)
W = 170 N
