Answer:
Step-by-step explanation:
The mass of lead cylinder is: 859.10 grams
Step-by-step explanation:
In order to find the mass of a cylinder we have to find the volume first
Given
Radius = r = 2 cm
Height = h = 6 cm
The volume of cylinder is given by:

Putting the values

Now,
Density of lead per cm^3 = 11.4g

Answer:
f(3)=1
Step-by-step explanation:
take f(x)=2(x)-5
put a three wherever you see an x in parentheses
f(3)=2(3) - 5
simplify
f(3)=6-5
simplify
f(3)=1
answer:f(3)=1
