Please help i am having trouble with it

904.32

Step-by-step explanation:

First calculate the smaller cylinder (It really doesn't matter which you do first though) by finding the area of it. Do this by multiplying (pi)(radius)^2 or (pi)(3)^2 because the radius of the smaller circle is 3. Once you do it multiply by 18 to find the cylinder area. Do the same steps for the big circle (10cm in diameter) and then subtract the smaller cylinder from the bigger cylinder.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
