Question

area and the circumference of a circle with radius 9 ft. value 3.14 for π, and do not round your answers. be sure to include the correct units in your ans

Explanation:

Step1: Calculate the area of the circle

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(r = 9\) ft and \(\pi=3.14\), we substitute the values: \(A=3.14\times9^{2}=3.14\times81\).

Step2: Calculate the circumference of the circle

The formula for the circumference of a circle is \(C = 2\pi r\). Substituting \(r = 9\) ft and \(\pi = 3.14\), we get \(C=2\times3.14\times9=6.28\times9\).

Answer:

Area: \(254.34\) square feet
Circumference: \(56.52\) feet
