Calculate the volume of a cylindrical steel bar which is 8cm long and 3.5cm in diameter
pi r^2 h = pi * (3.5/2)^2 * 8 cm^3
Please can you solve the question for me
Answer
To calculate the volume of a cylindrical steel bar, you can use the formula:
Volume = π * (radius)^2 * height
Here's how you can find the volume of the steel bar with the given dimensions:
1. Convert the diameter to radius by dividing it by 2.
Radius = diameter / 2 = 3.5 cm / 2 = 1.75 cm
2. Use the formula to calculate the volume.
Volume = π * (1.75 cm)^2 * 8 cm
Volume ≈ 3.14 * (1.75 cm)^2 * 8 cm
Volume ≈ 3.14 * 3.0625 cm^2 * 8 cm
Volume ≈ 77.15 cm^3
Therefore, the volume of the cylindrical steel bar is approximately 77.15 cm^3.
