Final answer:
To convert 8 meters to centimeters, multiply by 100 to get 800 centimeters. For the circumference of a tree's ring with a diameter of 8 inches, use the formula C = πd, which results in approximately 25.13 inches.
Step-by-step explanation:
Converting Meters to Centimeters
To find out how many centimeters are in 8 meters, we need to know the basic conversion factor between meters and centimeters. There are 100 centimeters in 1 meter. Thus, to convert 8 meters into centimeters, you multiply 8 by 100:
8 meters × 100 centimeters/meter = 800 centimeters.
Calculating the Circumference of a Circle
The question asks for the circumference of a tree's ring with a diameter of 8 inches. The formula for the circumference (C) of a circle is C = πd, where π is approximately 3.14159 and d is the diameter. Substituting 8 inches for the diameter, we get:
C = π × 8 inches ≈ 3.14159 × 8 inches ≈ 25.13 inches.
Therefore, the circumference of the tree's ring is approximately 25.13 inches.
