Volume of Cylinder

radius = 9, height = 40

Answer:

10179 cubic units

Shape Visualization

Cylinder with radius 9 units and height 40 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 × 40 = 10179
4

Final answer

Volume = 10179 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 40m height holds 10179 cubic meters

2

A can with 9 inch radius and 40 inch height = 10179 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.
