Answer:
0.7 m or 70 cm
Step-by-step explanation:
We are given;
- Volume of a cylinder as 1.54 cm³
- Diameter of the base as 140 cm
We are required to determine the height of the cylinder
We need to know how to find the volume of a cylinder.
Volume of a cylinder is given by the formula;
Volume = πr²h
r = d/2 = 70 cm
But, 100 cm = 1 m
thus, radius = 0.7 m
Rearranging the formula;
H = Volume ÷ πr²
= 1.54 m³ ÷ (22/7 × 0.7²)
= 0.7 m
Thus, the height of the cylinder is 0.7 m or 70 cm
