Answer:
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 )

Answer:
Step-by-step explanation:
This might be familiar to you if you know about the pythagorean relationship in right triangle, aka pythagoras's theorem.
It states that, in a right triangle, the sum of the squares of the 2 shorter sides equals the square of the longest side, aka the hypotenuse.
Note that the triangle in this case is a right angled triangle, and all the surrounding shapes are squares.
So by the pythagorean relationship we have,
2^2 + 4^2 = c^2
4 + 16 = c^2
20 = c^2
c = sq root 20 = 2 * sq root 5
Hope it helps and if it does, plzzz mark me brainliest ;-)
