Question

Geometry help please

Answer 1

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!
