cylindrical-shaped aquarium is to be filled with water for the newly bought salt water fishes. How much salt water is needed if the aquarium has a 2 ft radius of its base and a height of 3 ft?
Volume = πr²h
V = (3.14) (2)² (3)
V = (3.14) (4) (3)
V = 37.68 ft³
37.68 ft³ of salt water is needed to fill the cylindrical aquarium.
Mr. Lee is buying a spherical water tank for his tomato plantation. How much water could be stored if the water tank has a radius of 2 meters?
Volume = (4/3) πr³
V = (4/3) (3.14) (2)³
V = (4/3) (3.14) (8)
V = (4/3) (25.12)
V = 33.493 m³
Mr. Lee can store 33.493 m³ of water in the spherical tank.

The correct statement proves that parallelogram KLMN is a rhombus.
The slope of KM is 1 and the slope of NL is –1.
<h3>What is the rhombus?</h3>
A rhombus is a parallelogram whose all sides are equal. Its diagonals perpendicularly bisect each other.
If one line is perpendicular to the other lines then the product of its slope should be -1.
The slope of the KM is;
The slope of the KM is 1.
And the slope of NL is;
The slope of NL is -1.
Hence, The slope of KM is 1 and the slope of NL is –1.
