Question

Find the volume of the cylinder. Use 3.14 for pi.

Option 1: 2826 cubic units
Option 2: 214 cubic units
Option 3: 133 cubic units
Option 4: 516.2 cubic units

Answer 1

To find the volume of a cylinder, use the formula V = πr²h and substitute the given values. The correct volume of the cylinder is approximately 9.278 cm³.

Step-by-step explanation:

To find the volume of a cylinder, we use the formula V = πr²h, where V represents the volume, r represents the radius, and h represents the height of the cylinder. In this case, we are given the value of pi as 3.14. Let's use the given formula to calculate the volume:

1. Substitute the values of the radius and height into the formula: V = 3.14 × (0.750 cm)² × 5.25 cm.
2. Simplify the equation: V = 3.14 × 0.5625 cm² × 5.25 cm.
3. Multiply the numbers: V ≈ 9.278 cm³.

Therefore, the correct option is Option 2: 9.278 cm³.
