Question

area of a circle
find the area of a circle with diameter 14 m.
use the value 3.14 for π, and do not round your answer.
be sure to include the correct unit in your answer.

Explanation:

Step1: Calculate radius from diameter

The radius $r$ is half the diameter.
$r = \frac{14}{2} = 7$ m

Step2: Apply circle area formula

Use the area formula $A = \pi r^2$, substitute $\pi=3.14$ and $r=7$.
$A = 3.14 \times 7^2 = 3.14 \times 49$

Step3: Compute final area

Calculate the product.
$A = 153.86$

Answer:

153.86 $m^2$
