Question

To construct a bracket for a drain​ pipe, a plumber needs to know its circumference. calculate the circumference of a pipe 40.8 cm in diameter

Answer 1

The circumference of a pipe with a diameter of 40.8 cm is calculated using the formula C = πd. By substituting 40.8 cm for the diameter and using approximately 3.14159 for π, the circumference is found to be approximately 128.14 cm.

Step-by-step explanation:

To calculate the circumference of a pipe with a diameter of 40.8 cm, we must understand the relationship between a circle's diameter and its circumference.


The formula for circumference is C = πd, where π (pi) is approximately 3.14159 and d represents the diameter.

Using the given diameter:

1. Substitute the diameter d = 40.8 cm into the formula.
   
2. Calculate the circumference C = 3.14159 × 40.8 cm.
   
3. The circumference of the pipe is then C ≈ 128.14 cm.
