Final answer:
To calculate the volume of a cylinder with a radius of 3 and a height of 4 using π as 22/7, the volume is found to be 132 cm³.
Step-by-step explanation:
The formula for the volume of a cylinder is given by V = πr²h.
To find the volume when r=3 and h=4, we can plug these values into the formula. If we use π as 22/7 for this calculation, the volume V is calculated as follows:
V = πr²h = (22/7) × (3 cm)² × (4 cm) = (22/7) × 9 cm² × 4 cm = (22/7) × 36 cm² = 132 cm²
Thus, the volume of the cylinder is 132 cm³.
