Question

1. a gardener is planning a circular flower bed with a radius of 3 meters. what is the area of the flower bed?

a. 28π sq m
b. 4.5π sq m
c. 9π sq m
d. 18π sq m

Explanation:

Step1: Recall the formula for the area of a circle

The formula for the area of a circle is \(A = \pi r^{2}\), where \(r\) is the radius of the circle.

Step2: Substitute the given radius into the formula

Given \(r = 3\) meters. Substitute \(r = 3\) into \(A=\pi r^{2}\), we get \(A=\pi\times(3)^{2}\).

Step3: Calculate the value of \(r^{2}\)

\((3)^{2}=3\times3 = 9\). So \(A = 9\pi\) square meters.

Answer:

C. \(9\pi\) sq m
