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

15.4%

Step-by-step 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 )

= π × 10² × 11 = 1100π ft³

= 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

× 100%

= × 100%

= × 100%

= 15.4% ( to the nearest tenth )

sorry I don't know this
