Volume of Cone

radius = 20, height = 10

Answer:

4188.8 cubic units

Shape Visualization

Cone with radius 20 units and height 10 units

Step-by-Step Solution

1

Identify the formula for volume of a cone

V = (1/3)πr²h
2

Square the radius

r² = 20² = 400
3

Multiply by π and height

π × 400 × 10 = 12566
4

Multiply by 1/3

(1/3) × 12566 = 4188.8
5

Final answer

Volume = 4188.8 cubic units

Formula Used

V = (1/3)πr²h

This formula calculates the volume of a cone.

Real-World Applications

1

An ice cream cone with 20 cm radius and 10 cm height holds 4188.8 cubic centimeters

2

A conical funnel 20 inches wide and 10 inches tall = 4188.8 cubic inches

Understanding Cone Volume

The volume of a cone is a fundamental concept in geometry. Volume measures the amount of space inside a 3D object, expressed in cubic units.

By using the formula V = (1/3)πr²h, we can quickly and accurately calculate the volume for any cone when we know the required measurements.
