Question

1. a circular garden has an area of approximately 254.34 square meters. which measurement is closest to the diameter of the circular garden in meters?

a 9 m
b 81 m
c 40.5 m
d 18 m

Explanation:

Step1: Recall circle area formula

$A = \pi r^2$

Step2: Solve for radius $r$

$r = \sqrt{\frac{A}{\pi}} = \sqrt{\frac{254.34}{3.14}} = \sqrt{81} = 9$

Step3: Calculate diameter $d$

$d = 2r = 2 \times 9 = 18$

Answer:

D. 18 m
