Question

what is the approximate area of the circle shown below? 16 cm (circle with center c) a. 25 cm² b. 804 cm² c. 50 cm² d. 201 cm²

Explanation:

Step1: Identify radius

The line through center is diameter: 16 cm. Radius $r = \frac{16}{2} = 8$ cm.

Step2: Calculate area

Area formula: $A = \pi r^2$. Substitute $r=8$: $A = \pi \times 8^2 = 64\pi$.

Step3: Approximate value

Use $\pi \approx 3.14$: $64 \times 3.14 = 200.96 \approx 201$ cm².

Answer:

D. 201 cm²
