Question

Determine the volume of this object

1) 113 mm
2) 226.1 mm
3) 339.1 mm
4) 450 mm

Answer 1

I believe 2 (226.1 mm) is the correct answer.
Step 1.

Find the circumference of the circle.
6(2)•3.14
37.68

Step 2. Multiply the circumference with the height (12mm)
37.68•12=452.16.

Final step: Divide your final answer by 2 because this object shown above is a cone.
452.16/2=226.08

Answer 2

I think it would be 450 mm.
