1️⃣ Pool A has more capacity than Pool B by 5744 cm³
2️⃣ Pool B has more capacity than Pool A by 5744 cm³
3️⃣ Pool A has more capacity than Pool B by 1976 cm³
4️⃣ Pool B has more capacity than Pool A by 1976 cm³
​

Answer 1

Step-by-step explanation:

3option is really good and right.

Answer 2

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

1

−V

2

=7000−1256

=5744m

3

Pool has more capacity than pool B by 5744m

3

Option (A) is correct
