Hello!

We first have to find the volume of the bigger cylinder

We use the equation \pi  r^{2} h

Put in the values you know

\pi 10.5^{2} *18

This is 6234.49

Now we find the volume of the cut out part

\pi  7.5^{2} 18

This is 3180.86

We subtract the two values

6234.49 - 3180.86 = 3053.63

The answer is 3053.6

Hope this helps!

If 4x^2 - 100 = 0 then the roots of the equation are
iVinArrow [24]
4x² - 100 = 0
<u>     + 100  + 100</u>
         <u> 4x²</u> = <u>100</u>
          4        4
           x² = 25
            x = <u>+</u>5
 4(5)² - 100 = 0
4(25) - 100 = 0
  100 - 100 = 0
               0 = 0

4(-5)² - 100 = 0
 4(25) - 100 = 0
   100 - 100 = 0
                0 = 0

The roots of the equation is positive or negative 5.
