Question

1. find the circumference. 20.5 ft

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle with diameter $d$ is $C = \pi d$.

Step2: Substitute diameter value

Substitute $d = 20.5$ ft into the formula:
$C = \pi \times 20.5$

Step3: Calculate the result

Using $\pi \approx 3.14$, compute:
$C \approx 3.14 \times 20.5 = 64.37$

Answer:

64.37 feet
