Question

Please help me i’ve tried so many of these and i can’t figure out how to do it

Answer 1

15.4%

Explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

`V_(A)` = π × 10² × 11 = 1100π ft³

`V_(B)` = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

`(left)/(full)` × 100%

=
`(169\pi )/(1100\pi )` × 100%

=
`(169)/(1100)` × 100%

= 15.4% ( to the nearest tenth )
