### Volume of Solid rotating calc question, am i doing it right?

Can someone tell me if Im doing this right?

So for part a, i think the answer would be the integral of (2-8-x^2)^2 - (2-x^2)^2 times pi from -2 to 2.

Im not sure how to do b or c so can someone explain that part?

Write the three different ways we could find the EXACT area under 𝑓(𝑥) = 𝑒^𝑥^3 on any interval [a,b].

I tried working on it and the only way I could figure out was was the integral way. I didn't know there were more so can someone help?

A certain chemical reaction releases 423.kJ of heat energy per mole of reactant consumed. Suppose some moles of the reactant are put into a calorimeter (a device for measuring heat flow). It takes 2.79J of heat energy to raise the temperature of this calorimeter by 1°C. Now the reaction is run until all the reactant is gone, and the temperature of the calorimeter is found to rise by 12.9°C. How would you calculate the number of moles of reactant that were consumed?

Set the math up. But don't do any of it. Just leave your answer as a math expression.

Also, be sure your answer includes all the correct unit symbols.
