Answer:
> cylindrical tank
> holds more water by 9.699 m³
Step-by-step explanation:
Cylindrical tank:
r = 4/2 = 2m
h = 3m
Volume: V = πr²h
V = π(2)²(3) = 12π = 37.69911184 m³
Rectangular tank:
Volume: V = lwh
V = 7 * 2 * 2 = 28 m³
37.699 > 28
37.699 - 28 = 9.699
Cylindrical water tank holds more water by 9.699 m³.
cylindrical water tank
by 9.7 cubic meters
Step-by-step explanation:
Cylinder
V=πr²h
V=(3.14)(2)²(3)=37.7
rectangular prism
v=lwh
v=(7)((2)(2)=28
37.7-28=9.7
