Answer 1

C, They have the same volume

Explanation:

1 x 6= 6

and

2 x 3= 6

Answer 2

A. The red cylinder

Explanation:

Which cylinder has the greater volume

volume of a cylinder

formula:

V =
`\pi r^(2) h`

volume of the blue cylinder

V =
`\pi r^(2) h`

=
`\pi * 1^(2) * 6`

=18.84956

to 2 dp

volume of the blue cylinder is 18.85

volume of the red cylinder

V =
`\pi r^(2) h`

=
`\pi * 2^(2) * 3`

= 37.69911

to 2dp

volume of the red cylinder is 37.70

the cylinder which has the greater volume is : A. The red cylinder
