To find the circumference and area of a circle, you can use the following formulas:

  1. Circumference (C) of a circle:
    \[ C = 2 \pi r \]

  2. Area (A) of a circle:
    \[ A = \pi r^2 \]

Given radius (r) = 38 feet and using \(\pi \approx 3.14\):

Calculating Circumference:

\[ C = 2 \times 3.14 \times 38 \]
\[ C = 6.28 \times 38 \]
\[ C = 238.64 \text{ feet} \]

Calculating Area:

\[ A = 3.14 \times (38^2) \]
First calculate \(38^2\):
\[ 38^2 = 1444 \]
Now calculate the area:
\[ A = 3.14 \times 1444 \]
\[ A = 4537.76 \text{ square feet} \]

Summary of results:

  • Radius: 38 ft.
  • Circumference: 238.64 ft.
  • Area: 4537.76 ft²
