Second moment of area about an axis along any diameter in the plane of the cross section (i.e. x-x, y-y) is each equal to (1/4)pi r^4.
The second moment of area about the zz-axis (along the axis of the cylinder) is the sum of the two, namely (1/2)pi r^4.
The derivation is by integration of the following:
int int y^2 dA
over the area of the cross section, and can be found in any book on mechanics of materials.
Each term is (the previous term increased by 20).
The next 3 terms are <em>114, 134, 154 .</em>
Answer:
I'm not even lying, it's none of them ;-;

Answer:
District 221221221. I'm not really sure cause last days of snow each school district some of the school tallied
Answer:
I believe the answer is 7/20 or 35%.
Step-by-step explanation:
I first started by subtracting the coins that we already know from the total, and I get 7. I put that in fraction form which is, 7/20 and I turned it into percent form which is 35%. I hope one of these answers helps.
