Question

1. find the area. use 3.14 for pi and round your answer.

circle with diameter 15.5 m

Explanation:

Step1: Calculate the radius

The radius $r$ is half the diameter.
$r = \frac{15.5}{2} = 7.75$ m

Step2: Apply area formula for circle

Use $A = \pi r^2$, substitute $\pi=3.14$ and $r=7.75$.
$A = 3.14 \times (7.75)^2$

Step3: Compute the squared radius

Calculate $7.75^2$ first.
$7.75^2 = 60.0625$

Step4: Calculate final area

Multiply by 3.14 and round.
$A = 3.14 \times 60.0625 = 188.59625 \approx 188.60$

Answer:

$\boldsymbol{188.60}$ square meters
