Question

The Cole family owns an above-ground circular swimming pool that has walls made of aluminum. Find the length l of aluminum surrounding the pool as shown if the diameter of the pool is 30 feet. Round your answer to the nearest tenth of a foot.

Answer 1

basically, you're solving for circumfrence, so circumference=2$\pi$r.
2r is diameter, so 3.1415926 multiplied by 30 is about 94.2 ft.

Answer 2

Here, The length of the aluminum means, the Circumference of that Circle.

We know, Circumference = π * Diameter.

C = 3.14 * 30 = 94.2 Feet

In short, Your Final Answer would be: 94.2 Feet

Hope this helps!
