Question

find the area and the circumference of a circle with radius 8 ft. use the value 3.14 for π, and do not round your answers. be sure to include the correct units in your answe area: circumference:

Explanation:

Step1: Calculate the area of the circle

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(r = 8\) ft and \(\pi=3.14\), we substitute the values: \(A=3.14\times8^{2}=3.14\times64 = 200.96\) \(ft^{2}\).

Step2: Calculate the circumference of the circle

The formula for the circumference of a circle is \(C = 2\pi r\). Substituting \(r = 8\) ft and \(\pi = 3.14\): \(C=2\times3.14\times8=50.24\) ft.

Answer:

Area: \(200.96\) \(ft^{2}\)
Circumference: \(50.24\) ft
