Question

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

Explanation:

Step1: Calculate the area of the circle

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(r = 9\) m and \(\pi=3.14\), we substitute the values: \(A=3.14\times9^{2}=3.14\times81 = 254.34\) \(m^{2}\).

Step2: Calculate the circumference of the circle

The formula for the circumference of a circle is \(C = 2\pi r\). Substituting \(r = 9\) m and \(\pi = 3.14\), we get \(C=2\times3.14\times9= 56.52\) m.

Answer:

Area: \(254.34\) \(m^{2}\)
Circumference: \(56.52\) m
