Acircular swimming pool has a diameter of the 26 feet. what is the area of the swimming pool? use 3.14 to approximate for π . enter your answer, as a decimal rounded to the nearest tenth, in the box.

The area of a circle is given by the following formula:



r is the radius of the circle.

We are given a diameter of 26 feet. Because the area formula uses the radius, we must divide the diameter by 2 to find the radius:



The radius of the swimming pool is 13. Now we can plug in all of our values into the formula:






Because we are rounding to the tenths place, look at the hundredths digit:

530.66
6 > 5
530.66 -> 530.7

The area of the swimming pool rounded to the nearest tenth is 530.7 square feet.
