Answer:
Step-by-step explanation:
The volume of the cylinder is
where r is the radius of a base circle and h is the cylinder's height.
If cylinder has diameter of 8 inches, then its radius is 4 inches. The height of the cylinder is 5 inches. Thus, the volume of the cylinder is
The volume of the cone is
where r is the radius of a base circle and h is the cone's height.
If cone has diameter of 8 inches, then its radius is 4 inches. The height of the cone is 15 inches. Thus, the volume of the cone is
As you can see the cylinder and the cone have the same volume.
Hello!
If By = 52 then m<BAY = 26
m<BAC = 90
m<BAC = m<BAY + m<YAC
Substitute the values we know
90 = 26 + m<YAC
Subtract 26 from both sides
64 = m<YAC
The answer is B
Hope this helps!

Answer:
t = 6162 years
Step-by-step explanation:
Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.
The equation to use is that for carbon decay:
If the skull contains 54% of its original amount of C14, then that means that :
we use this to solve for the time (t) in our equation:
which rounded to the nearest year as requested gives :
t = 6162 years
