Answer:
1.11 mm
Step-by-step explanation:
The height of a cylinder can be found using the formula: h=V/(πr^2)
This formula was found by taking the formula for the volume of a cylinder and solving for h, or height. Knowing that V is 126 and the radius is 6, we can plug in our known variables in order to solve for h.
Answer:
7000 mm
Step-by-step explanation:
Volume of the cylindrical rod = 126 m^3
Radius of the cylindrical rod= 6m
π = 3.14 (approximately)
Required: h(in mm)
Volume of a cylinder = πr^2h
126 m^3 = (6)^2 * h
or
h= 126/ (6)^2= 126/ 36= 6.6868m* 1000= 6686.8mm
Therefore, the height of the cylinder is 7000 mm to its closest approximation.
