Find the circumference and the area of a circle with radius 2 ft.

Question

Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

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

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

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

Given that the radius \(r\) is 2 ft and using \(\pi \approx 3.14\):

1. Calculating the Circumference: \[ C = 2 \times 3.14 \times 2 = 12.56 , \text{ft} \]

2. Calculating the Area: \[ A = 3.14 \times (2^2) = 3.14 \times 4 = 12.56 , \text{ft}^2 \]

Thus, the circumference of the circle is \(12.56 , \text{ft}\) and the area is \(12.56 , \text{ft}^2\).
