Question

find the area of a circle with diameter 10 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 the radius

The radius $r$ is half the diameter.
$r = \frac{10}{2} = 5$ m

Step2: Apply area formula for circle

Use the formula $A = \pi r^2$, substitute $\pi=3.14$ and $r=5$.
$A = 3.14 \times 5^2 = 3.14 \times 25$

Step3: Compute the final area

Calculate the product.
$A = 78.5$

Answer:

78.5 $m^2$
