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!

\rm \looparrowright -  \frac{1}{4} (8 - 4 + 20x)

Subtract the numbers

\rm \looparrowright -  \frac{1}{4} (4+ 20x)

Factor out 4 from the expression

\rm \looparrowright   - \frac{1}{ \cancel4}  \times  \cancel4(1 + 5x)

\rm \looparrowright   - (1 + 5x)

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

\rm \looparrowright   - 1  -  5x

  • <em>Thus, Options A and F are correct!!~</em>
