Introduction

In geometry, a right circular cone is a three-dimensional shape with a circular base and a vertex that is directly above the center of the base. The volume of a cone is an essential concept in mathematics, and it has numerous real-world applications in fields such as engineering, architecture, and physics. In this article, we will explore the formula for finding the volume of a right circular cone and provide a step-by-step guide on how to calculate it.

Understanding the Formula

The formula for finding the volume of a right circular cone is given by:

V = (1/3)πr²h

Where:

V is the volume of the cone
r is the radius of the base of the cone
h is the height of the cone
π is a mathematical constant approximately equal to 3.14

Calculating the Volume of a Right Circular Cone

Now that we have the formula, let's calculate the volume of a right circular cone with a base radius of 10 cm and a height of 7 cm.

Step 1: Identify the Given Values

r = 10 cm (base radius)
h = 7 cm (height)

Step 2: Plug in the Values into the Formula

Substitute the given values into the formula:

V = (1/3)π(10)²(7)

Step 3: Simplify the Equation

Simplify the equation by squaring the radius and multiplying it by the height:

V = (1/3)π(100)(7)

Step 4: Multiply the Numbers

Multiply the numbers together:

V = (1/3)π(700)

Step 5: Calculate the Volume

Now, multiply the result by π (approximately 3.14) and divide by 3:

V ≈ (1/3)(3.14)(700)

V ≈ 733.33

Therefore, the volume of the right circular cone with a base radius of 10 cm and a height of 7 cm is approximately 733.33 cubic centimeters.
