Answer 2

Answer:

798.336 m³

Step-by-step explanation:

Given:

• Radius of a wooden log = 8.4 m
• Length of a wooden log = 3.6 m

To find:

• The volume of a wooden log in cubic metre.

Solution:

Here, we will use formula to calculate the volume of cylindrical log i.e, πhr². Putting the values in the formula and then doing required calculations we can easily find the value of volume of a wooden log.

• Volume of wooden log = πhr²

Here,

• The value of π is 22/7
• h is the length of a wooden log.
• r is the radius of a wooden log.

Putting the values in the formula, we have:

• Volume of wooden log = 22/7 × 3.6 × 8.4²
• Volume of wooden log = 22/7 × 3.6 × 8.4 × 8.4
• Volume of wooden log = 22/7 × 3.6 × 70.56
• Volume of wooden log = 22 × 3.6 × 10.08
• Volume of wooden log = 22 × 36.288
• Volume of wooden log = 798.336 m³

∴ The volume of a wooden log = 798.336 m³
