All you have to do is simplify each term. And by doing so, you will get 4y^-4 + 2 - 1
You can't that's as simple you can get
Ok, so what you would have to do is plug in all the variables you have provided into the equation. so you should get the equation:
2 (3.14)(2squared)+2 (3.14)(2)(4) <- you get the 4 from multiplying the radius by 2, which will give you the diameter, but it will also give you the height. So just do the math from there. So by putting it into my calculator, I got 74.72.
Savings accounts generally generate more interest than checking accounts, and it is also harder to spend out of savings than checking.
