Question

A circular 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.

Answer 1

So the equation for the area of a circle is $A=3.14(r^2)$

First to find the radius, you would need to divide the diameter, 26, by half, which in this case its 13.

Replace the r variable with 13 and solve:

$A=3.14(13^2)$

$A=3.14(169)$

$A=530.7$
