Question

A hotel swimming pool is made for semi circle and square. Find The perimeter of the swimming pool. Round your answer to the nearest tenth.

Answer 1

Combining the 4 semi-circles of the pool, we can make 2 circles, with a diameter of 10 yd.

The perimeter of a circle is calculated as follows:

$P=\pi\cdot D$

where D is the diameter.

Then, the perimeter of the swimming pool is:

$\begin{gathered} P=2\cdot\pi\cdot10 \\ P=62.8yd^{} \end{gathered}$
