Question

Hey!!!!!!!! Help me :)
A funnel with a height of 3.42 inches is shown below.
The funnel has a diameter of 1.56 inches that includes a wall that is 0.125 inches thick. What is the maximum volume of the funnel rounded to the nearest hundredth?
1.54 in3
6.54 in3
2.18 in3
1.18 in3

Answer 1

The answer is 1.54 in^3

Answer 2

See u got to subtract twice the width of the wall from the diameter which gives u d=1.31 in

So your r=0.655 in

Then apply the formula for volume of cone \[1/3\pi r ^{2} h\]

Answer 3

Thank you!
