Answer 1

What is the area of a circular pool 6.5 meter in diameter/ (square unit in metric are represented with a raised 2 after abbreviation)

Solution.

The area of a circle is

$$S = \pi R ^ {2},$$

where $\pi = 3.14\ldots$

$R$ is a radius of the circle and $R = \frac{d}{2}$, where $d$ is diameter of the circle.

Then we have

$$S = \pi \left(\frac {6.5}{2}\right) ^ {2} \approx 33.18\ (meter ^ {2})$$

Answer:

$$33.18\ (meter ^ {2})$$
