Question

1. find the circumference.

Explanation:

Step1: Identify given diameter

The diameter $d = 15.5\ \text{m}$.

Step2: Use circumference formula

Circumference $C = \pi d$. Substitute $d$:
$C = \pi \times 15.5$
Using $\pi \approx 3.14$:
$C \approx 3.14 \times 15.5$

Step3: Calculate the product

$3.14 \times 15.5 = 48.67$

Answer:

$48.67\ \text{m}$
