Volume of Cone

radius = 7, height = 20

Answer:

1026.3 cubic units

Shape Visualization

Cone with radius 7 units and height 20 units

Step-by-Step Solution

1

Identify the formula for volume of a cone

V = (1/3)πr²h
2

Square the radius

r² = 7² = 49
3

Multiply by π and height

π × 49 × 20 = 3078.8
4

Multiply by 1/3

(1/3) × 3078.8 = 1026.3
5

Final answer

Volume = 1026.3 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 7 cm radius and 20 cm height holds 1026.3 cubic centimeters

2

A conical funnel 7 inches wide and 20 inches tall = 1026.3 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.
