Question

Volume of right circular cylinder is twice the volume of the right circular cone. (True or false)

Answer 1

The given statement is false. Volume of right circular cylinder is not twice the Volume of right circular cone.
Let's us consider that, Radius and Height of Both Right circular cylinder and cone are equal. So,
Now,
Volume of right circular cylinder = πr²h
Volume of right circular cone = 1/3πr²h

Now, We observe that, Volume of cone and cylinder are in the ratio 1 : 3.

So, Volume of a right circular cylinder is thrice the Volume of right circular cone.

Answer 2

Volume of the right circular cylinder = π * (  r )^2 * h

Here,

π - 3.14

r - radius

h - height

Volume of the right circular cone = 1 / 3 π * (  r )^2 * h

Here,

π - 3.14

r - radius

h - height

And so,

The volume of the cone is 1 / 3 of the volume if the cylinder.

Hence, the statement is false.
