Question

what is the area of a circle with a diameter of 14 meters? leave the answer in terms of $pi$.
$49\pi$ square meters
$7\pi$ square meters
$196\pi$ square meters
$14\pi$ square meters

Explanation:

Step1: Find the circle's radius

Radius $r = \frac{\text{diameter}}{2} = \frac{14}{2} = 7$ meters

Step2: Apply circle area formula

Area $A = \pi r^2 = \pi \times 7^2$

Step3: Calculate the squared radius

$7^2 = 49$, so $A = 49\pi$

Answer:

A. 49π square meters
