14 cm: Finding the Volume of a Cylinder

Understanding the Problem

When dealing with cylinders, it's essential to understand the formula for finding their volume. The volume of a cylinder can be calculated using the formula V = πr²h, where V is the volume, π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the cylinder's base, and h is the height of the cylinder. In this problem, we are given the height of the cylinder as 6 cm and the radius as 3 cm. We need to find the volume of the cylinder using the given values.

Given Values

  • Height (h) = 6 cm
  • Radius (r) = 3 cm
  • Pi (π) = 3.14

Applying the Formula

To find the volume of the cylinder, we need to substitute the given values into the formula V = πr²h.

V = πr²h V = 3.14 * (3)² * 6 V = 3.14 * 9 * 6 V = 3.14 * 54 V = 170.76

Rounding the Answer

Since the answer is not required to be in decimal form, we can round it to the nearest whole number. However, in this case, we will keep the answer in decimal form for accuracy.

The Final Answer

V = 170.76 cm³

Discussion

The formula for finding the volume of a cylinder is V = πr²h. This formula is derived from the fact that the volume of a cylinder is equal to the area of its base multiplied by its height. The area of the base is given by the formula A = πr², where A is the area and r is the radius of the base. When we multiply this area by the height of the cylinder, we get the volume of the cylinder.

In this problem, we used the formula V = πr²h to find the volume of a cylinder with a height of 6 cm and a radius of 3 cm. We substituted the given values into the formula and calculated the volume to be 170.76 cm³.

Real-World Applications

The formula for finding the volume of a cylinder has numerous real-world applications. For example, in architecture, the volume of a cylinder can be used to calculate the amount of materials needed for construction. In engineering, the volume of a cylinder can be used to calculate the amount of fluid that can be stored in a tank. In science, the volume of a cylinder can be used to calculate the amount of gas that can be stored in a container.

Conclusion

In conclusion, finding the volume of a cylinder is a simple process that involves substituting the given values into the formula V = πr²h. By understanding the formula and applying it correctly, we can calculate the volume of a cylinder with ease. The formula for finding the volume of a cylinder has numerous real-world applications and is an essential concept in mathematics and science.
