Answer: 536.94 g
Step-by-step explanation:
First, we know that:
mass = density*volume
We already know the density of the gold, this is:
19 g/cm^3
So we only need to find the volume of the gold medal.
We can think of the medal as a cylinder.
For a cylinder of diameter D and height H the volume is:
V = pi*(D/2)^2*H
where pi = 3.14
For the case of the medal, we have that:
D = 6cm
H = 1cm
Then the volume of the medal is:
V = 3.14*(6cm/2)^2*1cm = 28.26cm^3
Now that we know the volume of the medal, we can find the mass if we use the first equation:
Mass = (19 g/cm^3)*(28.26 cm^3) = 536.94 g
So first you write it as an improper fraction. So 2 1/9 would be 19/9
ITS B. The range is the stuff in the right circle. So its 245
Answer:
C 180-123
Step-by-step explanation:
This is because 180 is what triangles always equal and if one angle is 128 then the rest will be answered from this equation
