Volume of Cylinder

radius = 9, height = 20

Answer:

5089.4 cubic units

Shape Visualization

Cylinder with radius 9 units and height 20 units

Step-by-Step Solution

1

Identify the formula for volume of a cylinder

V = πr²h
2

Square the radius

r² = 9² = 81
3

Multiply by π and height

π × 81 × 20 = 5089.4
4

Final answer

Volume = 5089.4 cubic units

Formula Used

V = πr²h

This formula calculates the volume of a cylinder.

Real-World Applications

1

A cylindrical water tank with 9m radius and 20m height holds 5089.4 cubic meters

2

A can with 9 inch radius and 20 inch height = 5089.4 cubic inches

Understanding Cylinder Volume

The volume of a cylinder 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 = πr²h, we can quickly and accurately calculate the volume for any cylinder when we know the required measurements.
