Correct option is
A
Pool A has more capacity than Pool B by 5744cm
3
Pool A
Shape- rectangular
length =40m
width = 35m
Depth = 5m
Volume of rectangle ⇒length×width×depth
=40×35×5
=7000m
3
Pool B
Shape- Cylindrical
Diameter =20m
Radius(r) = 10m
Depth (h) =4m
Volume =πr
2
h
=π(10×10)×4
=400π
=1256 m
3
Difference between (A) and (B)
V

=7000−1256
=5744m
3
Pool has more capacity than pool B by 5744m
3
Option (A) is correct
