Answer with Step-by-step explanation:
We know that volume of a cylinder with radius r and height h is:
πr²h
and volume of cone with radius r and height h is:
πr²h/3
Volume of cone=Volume of cylinder/3 < Volume of cylinder
Volume of cylinder=84π in² where π=3.14
Volume of cone=84π/3 in²
= 84(3.14)/3 in²
Hence, correct options are:
The volume of the cone is 1/3 the volume of the cylinder.
The volume of the cone is less than the volume of the cylinder.
The expression 84(3.14)/3 finds the volume of the cone.
