Solve for the circles area, round up to three decimal places: substitute only.
Given; diameter = 17 cm.
Radius = ?
Area = ?

(A = π r²)


Sagot :

Answer:

To solve for the area of a circle using the diameter given, follow these steps:

1. ** the radius (r)**: The radius is half of the diameter.

\[

r = \frac{diameter}{2} = \frac{17 \, \text{cm}}{2} = 8.5 \, \text{cm}

\]

2. **Calculate the area (A)**: Use the formula \( A = π r² \).

\[

A = π (8.5 \, \text{cm})²

\]

First, calculate \( (8.5)² \):

\[

(8.5)² = 72.25 \, \text{cm}²

\]

Now, multiply by π (approximately 3.14159):

\[

A ≈ 3.14159 \times 72.25 \approx 227.285 \, \text{cm}²

\]

3. **Round to three decimal places**:

\[

A ≈ 227.285 \, \text{cm}² \text{ rounded to three decimal places is } 227.285 \, \text{cm}².

\]

Thus, the area of the circle is approximately **227.285 cm²**
